Hello,

Lately, the emails sent to this Scilab users mailing as plain text have several carriage returns omitted.
Why is this so and what is the workaround?

Sending as html does not seem to be a bullet proof solution either and such emails quickly bounce back if size>100kb, which is a rather low threshold.

Thanks and regards,

Hi,

On a Intel(R) Core(TM) i3-3220T CPU @ 2.80GHz (Linux), the following code
needs ~8s and
it doesn't allocate that much memory.

n=20000;
r=23;

radius = r*grand(n,1,'def').^(1/3);

phi = 2*%pi*grand(n,1, 'def');

costheta = 1 - 2*grand(n,1, 'def');

radsintheta = radius.*sin(acos(costheta));

X = [radsintheta.*cos(phi),radsintheta.*sin(phi), radius.*costheta];

ONE=ones(n,1);
NAN=[%nan,%nan,%nan];
SUM=[1;1;1];

MinDist=zeros(1,n);

for i=1:n;

    XX = X;
    XX(i,:) = NAN;
    DIFF = XX - ONE*X(i,:);
    MinDist(i) = sqrt(min((DIFF.*DIFF)*SUM));

end;

Cheers,

wozai

Hi all,

I hope that the following will stop the (useless) competition : if speed 
is a real bottleneck for this particular computation, using plain C is 
the only option. The self-contained script (n=20000) given at the end of 
this message gives the following timings on various hardware (only one 
processor core is used) :

2,8 GHz Quad-Core Intel Xeon : 1.08 s (OSX)
2.2 GHz Xeon(R) CPU E5-2660 v2 @? : 1.84 s (Linux)

Don't use plain Scilab if speed is a crucial issue....

For me it's fun to see thevarious attempts at improving speed. Thanks to
Stephane for the x*x tip being better than x^2.

Hi JP

Thanks. Before asking in the forum I did find the grivet.sce file by Google
search. To me the xfpoly solution looked like a 2D plot... I'll check your
attached code again, maybe I'll have a revelation :-)

Best regards
Claus

Subject: [Scilab-users] xget("fpf") xset("fpf") => gca().ticks_format(4)?
Message-ID: <9affd59f-cd70-8bc9-0c4c-fea3dfa277ea@free.fr>

Please follow up the discussion on the devs@ list only.

Dear devs and users,

xset() and xget() are obsolete since Scilab 5.0. Yet, they still remain 
in Scilab 6.0 due to the xget("fpf") and xset("fpf") syntaxes that still 
have no replacement.

These syntaxes respectively gets and sets the floating point C-like 
format of numbers to be labeled on level curves, as rendered by 
xstring() within contouring functions like contour2d() : 
https://help.scilab.org/docs/6.0.0/en_US/contour2d.html

The gca().ticks_format property was added in Scilab 5.5.0 and is now 
available.
It is currently a vector of 3 strings being C-like formats 
specifications for the labels of the x, y, and z axes.

So, i am wondering about the possibility to *replace the xget("fpf") and 
xset("fpf") with a fourth component gca().ticks_format(4) *(to be 
implemented).

Levels are (always?) about z, so in one hand it could be useless to 
implement .ticks_format(4) instead of using .ticks_format(3) that is 
already available. In another hand, the special value " " (blank) is 
presently used in contouring functions to cancel labeling, without 
canceling labels on the Z axis when contours are drawn in a 3D plot 
instead of a flat one.

Since, in Scilab itself, xget("fpf") and xset("fpf") are used only in 
leveling macros, *another solution *would be to

  * simply remove xget("fpf") and xset("fpf")
  * improve xnumb() in order to make it self-adaptable in term of
    display format according to values.
      o i already use and may provide such a version (as well to display
        complex numbers with their imaginary parts). A SEP may be prepared.
      o possibly add a formating option. But this is not mandatory if a
        self-adapting version is available in Scilab.
  * make contour(), contour2d() and contourf() using xnumb() instead of
    xstring(). This is trivial.
    Possibly add a labelling option to them (but it's not mandatory)

As a side question, adding a C-like format option to xstring() would be 
useful as well. The xstring() code already gets such a format from 
xget("fpf"). It would then be provided as a direct input, instead of 
from this former environmental variable.

I hope that Scilab will, ASAP, actually and properly get rid of these 
xget() and xset() functions.

May this contribution help to this purpose?

Best regards
Samuel

Hi Philippe

Thank you for poiting out that your book actually include this. I thought
"Fundamental" meant that it would be a bit too fundamental for me, but
maybe not. :-) ... I wish to also buy the other books in this series of
books, when made available in English.

Best regards,
Claus

"plain C is the only option": absolutely correct. As a matter of fact, I had programmed the problem in C in the first place. Idea was to probe the possibilty of Scilab, because that would make me more flexible with quick data handling and quick diagram sketches.

On my lowly Win10 laptop, the first rewrite from C to Scilab with doubly nested loop took 6h, change to vectorization of the inner loop 6min and further obvious smoothings 4min.

I am immensely greatful how to do the SciLab->C handover, all my previous attempts had failed and everything was extremely fast: tictoc=3.02

And the coding results in the correct solution as can be shown with
//  PLOT COMPARISON TO THEORY
dd=gsort(dist,'g','i');yy=(1:n)/(n+1);
scf;ii=0:.05:2.2;plot(ii,1-exp(-n*((ii/r).^3)),'r+');plot(dd,yy);
xtitle("Nearest Neighbour Distribution in 3d","distance (mm)","cumulative probability");
legend('prediction Prof Paul Hertz 1909','Monte-Carlo simulation of 20,000 points',pos=4);
//   END OF COMPARISON
I can send the diagram if somebody is interested.

Thanks a great lot, St?phane...
Heinz

Hi all,

I hope that the following will stop the (useless) competition : if speed is a real bottleneck for this particular computation, using plain C is the only option. The self-contained script (n=20000) given at the end of this message gives the following timings on various hardware (only one processor core is used) :

2,8 GHz Quad-Core Intel Xeon : 1.08 s (OSX)
2.2 GHz Xeon(R) CPU E5-2660 v2 @  : 1.84 s (Linux)

Don't use plain Scilab if speed is a crucial issue....

A new merged and improved version of param3d() and param3d1() pages
is commited and is proposed there in PDF:
http://bugzilla.scilab.org/attachment.cgi?id=4621

Please tell me about any unclear statement that could be still improved.
I hope that this will ease further works with 3D curves.

Regards
Samuel

PS1: new examples scripts are also proposed:

former param3d and param3d1 examples (equal):
	new param3d proposed example

new param3d1 example proposed (1D mesh plot):



PS2 : Beside being somewhat duplicates, the current pages have various 
issues:
https://help.scilab.org/docs/6.0.0/en_US/param3d.html
https://help.scilab.org/docs/6.0.0/en_US/param3d1.html

  * properties of curves are claimed to be some surface_properties
  * the point of view is claimed to be a polyline property (instead of
    an axes one)
  * etc.

Quite misleading, indeed...

Hello,

Heinz's interesting problem allows testing the Scilab limits and to learn
more about Scilab code optimization for very large datasets.
In the figure here below the execution times are plotted for the efficient
single loop code provided by Wozai and the modified vectorized code provided
further below.
<http://mailinglists.scilab.org/file/t495698/NN_problem_loop_and_vectorized.png> 

The execution times seem to increase with N^2 or worse... which does not
look very good. Maybe faster algorithms exist but lower level languages seem
definitely required for very large number of points. Thanks Stephane for the
example in C.

Scilab 6.0.0 complains about arrays with more than 2147483647 elements and
memory allocation problems are observed in Win7 32GB laptop when doing
computations with smaller matrices, far from that limit. A dummy example:
--> n=4e4; A = ones(n,1)*ones(1,n) + ones(n,1)*ones(1,n);
    Can not allocate 12800.00 MB memory.
However, >21GB of RAM are available.
Are these matrix size constraints going to be lifted in future Scilab 6
releases?


// START OF CODE (Scilab 6)
clear;
n= 30000;
r=23;
radius = r*grand(n,1,'def').^(1/3);
phi = 2*%pi*grand(n,1,'def');
costheta = 1 - 2*grand(n,1,'def');
radsintheta = radius.*sin(acos(costheta));
X = [radsintheta.*cos(phi), radsintheta.*sin(phi), radius.*costheta];
Xs = sum(X.*X,'c');
XX = Xs.*.ones(n,1)' + ones(n,1).*.Xs';  // faster than using transpose
XX = XX - 2*X*X';
XX(1:n+1:$) = %nan;  // remove diagonal 0's
MinDist1 = min(XX,'r').^0.5;   //min taken along rows is faster
clear  Xs  XX;
//END OF CODE

Thanks and regards,

Nearest neighbour search of n points requires n.(n+1)/2 comparisons,
therefore execution times proportional to n^2.

Hi Rafael

I've tried to make this code work for me, but ... (code):

// START OF CODE
frequencies = [201 811 3183 12862 25113]; // Hz;
angles = [0 30 60 90]; // deg
m_norm = [ 1.0   0.9945629   0.9643959   0.8756431;
           1.0   0.9914442   1.0244046   0.9414654;
           1.0   0.9910279   0.9670986   0.8932413;
           1.0   0.9339808   0.8378147   0.7067978;
           1.0   0.8985782   0.7536068   0.5074218];
[nf na] = size(m_norm)
A = (angles .*. ones(nf,1))';
F = (frequencies .*. ones(na,1));
M = 20*log10(m_norm'); // dB scale
clf();
sp = gca();
param3d1(F,A,M,alpha=50,theta=-110,flag=[2,4]);
e = gce();
for i=1:nf;
    e.children(i).foreground = color('dark blue');
    e.children(i).thickness = 2;
end
xgrid;
sp.log_flags = "lnn"; // x-axis log scale (frequencies)
sp.cube_scaling = "on";
xlabel("Frequency (Hz)");
ylabel("Angle (deg)");
zlabel("Mag (dB)");
// END OF CODE

The above code draws lines in the Y-axis direction. What I intended to do
is to draw lines in the frequency-direction (x-axis direction). I see how
e.children(i) manipulates the curves, but have failed to find a way to
change this (= the direction of the lines). I looked also at the examle
that Samuel gave with the plot3d3, where he draws a globe and can turn
lines on/off in the two directions ... I also looked at the latest proposal
by Samuel to updated param3d(1) and the lines in his last examples are
drawn along the x-axis direction.

Is the only solution to plot angle on x-axis and frequencies on y-axis?
(the rotate the cube differently) ...

(it's weird how one can stare at this for days without really understanding
what goes on)

Best regards,
Claus

Hi Claus,

On the basis of early code provided, I think you just need to transpose the matrix inputs to param3d1 in order to have the parametric curves plotted at fixed angles along <> frequencies. See below:


// START OF CODE
frequencies = [201 811 3183 12862 25113]; // Hz; row vector
angles = [0 30 60 90]; // off-axis angles, degrees
m_norm = [ 1.0   0.9945629   0.9643959   0.8756431;
           1.0   0.9914442   1.0244046   0.9414654;
           1.0   0.9910279   0.9670986   0.8932413;
           1.0   0.9339808   0.8378147   0.7067978;
           1.0   0.8985782   0.7536068   0.5074218];
[nf na] = size(m_norm)
A = (angles .*. ones(nf,1))';
F = (frequencies .*. ones(na,1));
M = 20*log10(m_norm'); // dB scale
clf();
sp = gca(); // Get current axis handle
param3d1(F',A',M',alpha=50,theta=-110,flag=[2,4]);
e = gce() //the handle on the 3D polyline
e.children.foreground = color('dark blue');
e.children.thickness = 2;
xgrid;
sp.log_flags = "lnn"; // x-axis log scale (frequencies)
sp.cube_scaling = "on";
xlabel("Frequency (Hz)");
ylabel("Angle (deg)");
zlabel("Mag (dB)");
// END OF CODE


Regards,
Rafael

Claus,

There are 2 distinct things:
a) the law you want to plot: Z(f)_theta or Z(theta)_f
b) the direction along which you want to plot the chosen law at the 
varying parameter

The only thing that you can't choose is that param3d1() plots each line 
from a particular triplet of X,Y,Z *columns*,
for all columns.
Then, you can do what you want.
Here is again the param3d1() example, but in an asymetric version (a 
long and a short sides):

[X,  Y]  =  ndgrid(-11:0.5:9,  -5:0.5:6);  // x is the long side, y the short one

clf
subplot(1,2,1)
R  =  sqrt(X.*X  +  Y.*Y)  +  %eps;
Z  =  sin(R)./R;
param3d1(X,  Y,  Z,  150,  85,  flag=[2,4])

subplot(1,2,2)
R  =  sqrt(X'.*X'  +  Y'.*Y')  +  %eps;
Z  =  sin(R)./R;
param3d1(X',  Y',  Z,  150,  85,  flag=[2,4])



Since this looks not trivial, i will change the example in the page to 
better illustrate both cases.

Cheers
Samuel

Hi Samuel

Thank you. This thing with the direction of the lines is difficult to
"discover" by accident. :-)

... And thanks for the good help for param3d(1). I hope Scilab will adopt
it.

Best regards,
Claus

When parts of curves are behind each others, there is a mess due to the 
perspective.
Here is a way to avoid this (i will also add it in the page):

[Xo,  Yo]  =  ndgrid(-10:0.5:10);
R  =  sqrt(Xo.*Xo  +  Yo.*Yo)  +  %eps;
Zo  =  sin(R)./R;

clf

// Simple plot with messed curves in the perspective
subplot(1,  3,  1)
param3d1(Xo,  Yo,  Zo,  150,  85,  flag=[2,4])

// With a curtain and filled curved (to avoid messed areas)
subplot(1,3,2)
nc  =  size(Xo,"c");
zmin  =  min(Zo);

X  =  [Xo(1,:)  ;  Xo  ;  Xo($,:)];
Y  =  [Yo(1,:)  ;  Yo  ;  Yo($,:)];
Z  =  [zmin*ones(1,nc)  ;  Zo  ;  zmin*ones(1,nc)];

param3d1(X,  Y,  Z,  150,  85,  flag=[2,4])
e  =  gce();
e.children.fill_mode  =  "on";

// Try to mask the curtain with %nan
// =>unsuccessful due to the bug http://bugzilla.scilab.org/11803
subplot(1,3,3)
X  =  [Xo([1  1],:)  ;  Xo  ;  Xo([$  $],:)];
Y  =  [Yo([1  1],:)  ;  Yo  ;  Yo([$  $],:)];
Z  =  [[zmin  ;  %nan]*ones(1,nc)  ;  Zo  ;  [%nan  ;  zmin]*ones(1,nc)];

param3d1(X,  Y,  Z,  150,  85,  flag=[2,4])
e  =  gce();
e.children.fill_mode  =  "on";

Hi Samuel

To be able to execute your example (using Scilab 6.0.0, MS Win7) I had to
provide ndgrid with two inputs:

[Xo, Yo] = ndgrid(-10:0.5:10,-10:0.5:10);


Cheers,
Claus

Message-ID: <CAN8qZzSBBOYJZPvd=N=8NWb=ZVZBpTfx=D_QV6oXasrMV-EV1g@mail.gmail.com>

The scilab-6.0.0 binary release was working on my xubuntu 17.4 system,
then I upgraded to 17.10 and since then I see the following error
message when I run the 'scilab' command:-

Cannot find this look and feel:
[GTK look and feel - com.sun.java.swing.plaf.gtk.GTKLookAndFeel] not

Segmentation fault (core dumped)

I see this issue has also been reported on bugzilla (
http://bugzilla.scilab.org/show_bug.cgi?id=15145 ) but I don't see any
workaround there, even though it seems to be marked as resolved.

Anyone know anything more?  Confused,

Paul

There seems to be little or no interest at all on this issue by scilab 
developers.

The only reply/workaround was provided by Clement David in the post you 
mention on Bugzilla, but it did not worked for me.

If you can count on a distro's builded version? of scilab 6.0, you have 
the option to install it.

I tried changing the thirdparty/java link to point to my system java
and/or moving the lib/thirdparty/libz* files as suggested in the
bugzilla discussion but got exactly the same results as reported by
adhefe (is that you?).  I also tried completely uninstalling all
system java packages and so just relying on the scilab-6.0.0 tarfile
java but the error message remains as I reported initially.
Reinstalling the system java didn't change anything either (which BTW
is 8u151-b12-0ubuntu0.17.10.2).

Unfortunately Ubuntu 17.10 still seems to be on Scilab 5.5.2.  I tried
compiling the latest source from git but get stuck during ./configure
with something else I don't understand:-

  configure: error: ARPACK library found, but seems not to work
properly. Please make sure you are using arpack-ng

Not sure if this is a known problem, haven't had chance to go into it yet.

Hi Claus,
Indeed, ndgrid(x) standing for ndgrid(x,x) was not yet available in the 
official 6.0.0 release, while i am using the 6.0.1.
It has been implemented in the meantime. 
<http://bugzilla.scilab.org/show_bug.cgi?id=15183>
Sorry for this misleading situation.
Cheers
Samuel

Hi Claus,
I tried to post an example of a stacked 2D plot but my post was held up 
due to a too large graphic
file (postscript). I have now converted this plot to png format. Here it 
is. Ypu may still be interested
in using the xpoly function, despite seeing Samuel's beautiful examples 
with param3d.
Cheers
Jean-Philippe

Dear Paul!

Seems to be incompatibility between upstream (Scilab.org) and GNU/Linux
distributions.

You can install scilab 6.0.0-1 packages from 18.04 LTS to your 17.10
as described
on AskUbuntu <https://askubuntu.com/a/1003065/66509>.

	Hi,

  I upgraded my mac to High Sierra 10.13.3 last week and Scilab 6.0.0 doesn?t start anymore. I tried to download the nighty build here : http://www.scilab.org/en/development/nightly_builds/branch60 <http://www.scilab.org/en/development/nightly_builds/branch60> and I get the 404 error : The requested URL /download/2017-08-02/scilab-branch-6.0-1500821730-x86_64.dmg was not found on this server. 
I would like to know if there is a fix to this situation. 

Any help would be greatly appreciated.

Thanks to all developers and contributors.

Philippe DEROGIS.

Hello,

It's the same with the master branch: 
http://downloadarea.scilab.org/download/2017-08-02/scilab-master-1501146348-x86_64.dmg 
gives a 404. That's the same for the windows link: 
http://downloadarea.scilab.org/download/2017-07-28/scilab-master-1501146348_x64.exe

Dear Scilaber's,

Will Octave be leveraged in Scilab as announced:
http://www.scilab.org/community/news/scilab-3Octave ?

In particular will some useful Octave functions such as bsxfun, which are compatible with Matlab, become available in Scilab?

Thanks and regards,
Rafael

	Hi Samuel,

  Thank you for your response, I dowloaded scilab-branch-6.0-macosx.tar but I didn't find any .dmg in it. It tried to run the stuff in the bin directory but it did not make anything interesting. Is there something that i missed ? 

Thank you

Philippe.

Hello,

If you already have scilab-6.0.0 :

-duplicate the scilab-6.0.0 app and rename it scilab.6.0.1
-right-click and "Show package content"
-navigate to Contents/MacOS folder
-drag and drop the files of the scilab-branch-6.0-macosx/ folder into 
the abovementioned folder (scilab-6.0.1.app/Contents/MacOS (say yes when 
prompted for overwriting files)

It worked for me.

A last (but not least) detail, copy the classpath.xml from scilab-6.0.0 
app to scilab-6.0.1 app :

cp scilab-6.0.0.app/Contents/MacOS/share/scilab/etc/classpath.xml 
scilab-6.0.1.app/Contents/MacOS/share/scilab/etc

Hi Nikolay,

Thanks for the suggestion.  I followed the instructions you linked to,
and succeeded in installing 6.0.0 from bionic, but unfortunately I
still get the same problem on startup:-

Cannot find this look and feel:
[GTK look and feel - com.sun.java.swing.plaf.gtk.GTKLookAndFeel] not
supported on this platform
Segmentation fault (core dumped)

I also tried 'scilab -nwni' to verify it was 6.0.0 I was running:-

Scilab 6.0.0 (Feb 14 2017, 12:49:55)

--> quit

So now I'm not sure what to try :-(

Paul

Oops, forget that last message!!!

I had accidentally left the old tarfile binary in my path and that's
why I was getting the same results (should have guessed that from the
-nwni timestamp, grrr).

Anyway, after removing it I can now start Scilab 6.0.0 in Ubuntu 17.10 :-)

Thanks Nikolay!

Hi,
I also followed the steps in my Ubuntu 17.10 but it just keeps installing scilab 5.5.2. Am i doing something wrong?

I seem to remember doing a "sudo apt update" after step 2, before step
3.  I also made sure I had removed the 5.5.2 release before trying
this, just to make sure things didn't get confused.  Though as shown
in my last message I still managed to confuse myself a little bit by
not removing the tarfile 6.0.0 release I had lying around :-)

Hope this helps,
Paul

	Hi,

  Stephane tried your solution but it doesn?t work for me. I am stuck?

I use to work a lot with scilab during the last twenty years, it is a great tool. I have a huge library of sci file that I built over those years and use them every days for my work (Acoustics and Signal Processing). But I find that unfortunately this tool is less and less reliable and become more a toy for geeks that love to spend hours on forums trying making things working on their computer. I am very disappointed that the owner (scilab enterprises) of a great application like scilab did not succeeded to maintain a working version of the application. 

On my side I will continue to check this mailing list daily in order to try to have things back up and running on my computer.

Sorry to have to say that.

Philippe Derogis

Hello Philippe,

Not really a technical point, but about your comment on :

> I am very disappointed that the owner (scilab enterprises) of a great application like scilab did
> not succeeded to maintain a working version of the application. 

As you may probably know, free software is a hard business and most of the Scilab team employees are
 currently providing support and services around the software for customers. The Windows and Linux
builds (from the CI on build.scilab.org) are used daily by the team and are improving from commits
to commits and, thanks to the contributors, we also validate the MacOS X version from time to time.

As you noted, your issue appeared after upgrading macOs; please take a look at the existing macOs
Sierra issues and write comment there. If you can contribute, do not hesitate to build Scilab
from source and help us getting a good quality MacOs support.

Thanks,

Hello Antoine, hello all,

The www.scilab.org website have not been updated yet but the nightly builds might be removed in
favor of the Continuous Integration builds [1]. The MacOs build [2] is a bit unreliable but might
provide your the latest binaries.

[2]: https://build.scilab.org/view/Scilab%20binaries/job/scilab-6.0-macosx/

Phillippe,

I am not sure if you have seen this work around listed in another thread:

Scilab 6.0.0 (the standar distribution, not the nightly build) worked
for me with Mac OS high sierra 10.13.3 by
removing these files:

/Applications/scilab-6.0.0.app/Contents/MacOS/lib/thirdparty/libBLAS.dylib
/Applications/scilab-6.0.0.app/Contents/MacOS/lib/thirdparty/libz.*

That may work for you while you wait for an updated Mac OS build to be
contributed.

Hi Cl?ment,

I totally understand your point and I am sure that all the employees are doing their best in order to have things working at their best. The thing that make me sade is that this great project initially from INRIA (I thing) do not succeed to become a profitable enterprise even it have the same potential as Matlab. I know that this have nothing to do with you guys but with the management of the company.

Thank you, for the clues for trying to run the application, I will try to mess around with that? one more time I?m note a software engineer but simply a guy that need a scientific computation software.

Philippe.

Hello Antoine, Tim,

Yep, for such issue, having a cross posting between a scilab bug and the ubuntu bug is a good idea.
This issue are sometimes possible to fix on Scilab side (but not relying for some GL features).

Hello Philippe,

I agree with you that any regression when Scilab, your graphic drivers or your OS gets updated is a real pain in the beep.
It's also clear that Scilab has some stability issues, in particular concerning its oversensitivity to graphic drivers?.
However, from my (limited) experience, I think you blame the wrong guy here: I ditched macos ages ago just because most of my daily open source softs were buggy and unreliable (scilab, inkscape, gimp, vlc, ...).
The situation is much better under linux or windows for most of them.
I'm not judging here the merits of macos, I just noticed that too many of the softs I depended on were working way better somewhere else...
As for the general trend for Scilab becoming less reliable over time, well I remember the good old times of Scilab 2.6. I don't miss it and think 6.0 is way more stable! :-)

Cheers,

Antoine
? I know that graphic drivers tend to be a big bundle of bugs, but when Scilab crashes because of graphic drivers issues, matlab, julia, and other java or openGL softs like paraview seem unaffected.

I have a huge library of sci file that I built over those years and use them every days for my work (Acoustics and Signal Processing).

I am very disappointed that the owner (scilab enterprises) of a great application like scilab did not succeeded to maintain a working version of the application.

Exact the `_ = gettext` has been stolen from the C usage of gettext. In C the '_' is defined as a
macro for gettext and is used for the same purpose: how to have the simplest identifier possible for
some hidden purpose ?

To me, Samuel proposition to deprecate "_" usage is really good; having "_" defined by default is
weird as there is two usage for this symbol (think from Go/Python users and from C users).

Thanks,

Thanks,
I solved it updating too. Anyway, that version is the one with input command bugged. I wish i could use a nigthly build where that bug is fixed. Also, trying to download a nigthly build lead me to 404 http error.

I seem to remember doing a "sudo apt update" after step 2, before step 3. I also made sure I had removed the 5.5.2 release before trying this, just to make sure things didn't get confused. Though as shown in my last message I still managed to confuse myself a little bit by not removing the tarfile 6.0.0 release I had lying around :-) Hope this helps, Paul _______________________________________________ users mailing list users at lists.scilab.org<mailto:users at lists.scilab.org> http://lists.scilab.org/mailman/listinfo/users

I saw it, but I've been thinking that a more recent release may exist
(in some personal archives?)

How to convert .wav to formula?

In scilab I can write like:

    t=soundsec(0.5);
    s=[sin(2*%pi*440*t)];
    savewave('foo.wav', s);

and by this convert formula to .wav.

But how can I convert .wav to formula? If I use

    analyze(loadwave('foo.wav'));

I only got graphic? What to do?

	Hi Ricardo,

  I tried your fix, then scilab was able to show up a window saying to install an old java package. I installed it and TADA? it worked. Thank to all of you guys for your help.

Message-ID: <b3eb0b4e-26e4-6c8a-36ce-29be01373106@utc.fr>

Hello all,

As you probably now, running Scilab on recent versions of OSX is not 
straightforward and althought the fixes are not that complicated, some 
users are reluctant to use the command line. The aim of this modest page

http://www.utc.fr/~mottelet/Darwin/

is to provide OSX applications were the interfering bundled libraries 
have been removed. The only remaining thing to do is to install the 
legacy Java 6 runtime (https://support.apple.com/kb/DL1572).

If something goes wrong please post a message on the mailing-list.

S.

Hi,

Q: "I only got graphic? What to do?"
A: look at Fourier synthesis of periodic waveforms.

For the toy example provided of a monochromatic wave, the simple code here below finds the approximate solution.
More general waveform case, needs much more programming effort.

// START OF CODE
clear; clf;
fs = 22050; // default sampling rate (Hz)
t=soundsec(0.5,fs);
s=[sin(2*%pi*440*t)];
savewave('foo.wav', s);

y = loadwave('foo.wav');
y = [y zeros(y)];  // make #samples even & increase spectral resolution
Yf = abs(fftshift(fft(y)));
N = length(Yf);
Yf = Yf(N/2+1:$);
f = linspace(0,fs/2-fs/N,N/2);
[y0 k] = max(Yf);
plot(f,Yf,'blue',f(k),Yf(k),'*red')

Friends:

I need to compute the spatial correlation coefficient of my x,y,z data in
3d.

Question 1: Is the MATLAB corrcoef function doing the job?
Question 2: How do I get corrcoef running in SciLab or C?

Hi Heinz,



Scilab computes the covariance matrix and from which the correlation matrix can be obtained using formula in https://en.wikipedia.org/wiki/Covariance_matrix



Check implementation below:


//START OF CODE
// https://en.wikipedia.org/wiki/Covariance_matrix
function Y=corrmatrix(M)
    C = cov(M);  // covariance matrix
    D = sqrt(diag(C)); // standard deviations
    D = inv(diag(D));
    Y = D*C*D;  // correlation matrix
endfunction

M = grand(9,3,"def")
M(:,2) = M(:,1)*2;
Y = corrmatrix(M);
disp(M,"M")
disp(Y,"Y")
// END OF CODE

Rafael

Do you mean the autocorrelation of a data(x,y,z) sampled distribution?
Or the intercorrelation of data(x,y,z) with a mask(x,y,z) function 
sampled on the same grid?
Or anything else?

Thanks. While not giving me ONE number, the analysis shows that my random
generated xyz positions are uncorrelated as they should. Can one estimate
the error bars for the xy xz and yz correlations?

 

Now, I can use this approach for actual measurements in real objects.

Sorry, I am lost.

I have 10,000 xyz data and want to know, if there is some regularity in them
or if they are more or less random. The concept of a mask does not come up
at all...

Hi Heinz,

can be obtained using formula in
https://en.wikipedia.org/wiki/Covariance_matrix

 

Check implementation below:

 

//START OF CODE

// https://en.wikipedia.org/wiki/Covariance_matrix

    C = cov(M);  // covariance matrix

    D = sqrt(diag(C)); // standard deviations

    D = inv(diag(D));

    Y = D*C*D;  // correlation matrix

endfunction

 

M = grand(9,3,"def")

M(:,2) = M(:,1)*2;

Y = corrmatrix(M);

disp(M,"M")

disp(Y,"Y")

// END OF CODE

 

For random generated xyz positions, I get the matrix below and this looks
fine with me:


1.000

-0.009

-0.003


-0.009

1.000

-0.001


-0.003

-0.001

1.000


 

 

 

                

 

But this here is a manufactured object and every singly xyz-value is
obtained from X-ray tomography

https://www.dropbox.com/s/87osn38agn8jfzo/Measured%2016867%20data%20points%2
0in%203d.png?dl=0

 

and looks much more regular than the Monte-Carlo. However, the correlation
analysis suggested here, gives much the same numbers.


1.000

-0.009

0.008


-0.009

1.000

-0.001


0.008

-0.001

1.000

 

Perhaps, I have asked the wrong question: 

 

 

-->what I need is one single figures that summarizes the spatial
correlation.

So you need and are speaking about the 3D autocorrelation of data(x,y,z).
Usually we compute it through a 3D convolution, that is easy to compute
through the FFT, noting that for an autocorrelation we just flip one of both
data array along x,y, and z before computing its FFT and going on with 
the algorithm.

Finally we use the inverse FFT to come back to the direct x,y,z space.
You may find good references on the web about the keyword 3D 
autocorrelation.

In scilab, you will mainly need

fft(A,sign,dims,incr[,option] )

since xcorr(), conv() conv2() convol2d() .. work only in 1D or 2D
(with too often duplicates to do the same thing, without "simple" 
extension to do more...)

Best regards
Samuel

1	The nearest neighbour distribution of N points in a 3d-Volume with
radius R is given by
W(r) = 1 - exp[ - N (r/r)^3] and this is a Weibull distribution and not a
Poisson distribution. The WIKI article, while correct, is a typical case
where high level statisticians are trying to make simple things look very
complicated.

2	Comparing the experimental distribution with the above prediction is
made complicated as the manufactured object has small hard spheres that push
each other apart in the manufacturing process and the Weibull is modified
anyway.

3	I am sill searching for a 3d spatial characterization coefficient
that differentiates between purely random arrangements and gradual regular
arrangements.

You may want to study this article:
https://pdfs.semanticscholar.org/574f/8f7347a258f6431fb8316716ca51b9b7eacb.p
df

it should give you a clue or two of what you may want to implement.

1	The nearest neighbour distribution of N points in a 3d-Volume with
radius R is given by
W(r) = 1 - exp[ - N (r/r)^3] and this is a Weibull distribution and not a
Poisson distribution. The WIKI article, while correct, is a typical case
where high level statisticians are trying to make simple things look very
complicated.

2	Comparing the experimental distribution with the above prediction is
made complicated as the manufactured object has small hard spheres that push
each other apart in the manufacturing process and the Weibull is modified
anyway.

3	I am sill searching for a 3d spatial characterization coefficient
that differentiates between purely random arrangements and gradual regular
arrangements.

Q: "I have 10,000 xyz data and want to know, if there is some regularity in
them or if they are more or less random"
A:  look for tests of spatial randomness
(https://en.wikipedia.org/wiki/Complete_spatial_randomness ) . If The
experimental nearest neighbor distribution obtained previously can be
compared to the expected Poisson distribution.

Subject: [Scilab-users] implicit polynomial / implicitlist
Message-ID: <ac718b95-9081-0ffd-097c-4436e9c4332a@free.fr>

Dear ESI devs,

In Scilab < 6, typeof(1:$) was "|size implicit"|

In Scilab 6.0, typeof(1:$) has become "implicitlist"

Why not.
The issue is that the overloading code is still "ip" standing for 
"implicit polynomial", not"il".
And in practical, this object is actually made of polynomial(s)

So, in one hand, for the same object, we refer to lists. On the other 
one, we refer to polynomials.
I don't know what was the motivation in renaming "|size implicit"| into 
"implicitlist".
If it was to remove an inconsistency somewhere, it apparently adds 
another one elsewhere.

So: why nottypeof(1:$,"overlaod")=="il" ?

It may still be the time to make the change consistent...

Regards
Samuel

Actually, i think that "implicitlist" is right.
"Size implicit" emphasized one usage (among other possible ones) : 
indexation.
"implicit polynomial" points to the components of the object, more than 
the object itself.

So this renaming is rather welcome and relevant. But now it would be 
even better to get a consistent overloading code.

Thanks for the many pointers. At this stage, although R is installed on my
computer, I would hesitate learning R just to run the Nathan Mantel test.
Can someone give me a helping hand in defining a spatial coordination index?
Using - in the first place - the random xyz coordinates below that we had
been using before for the nearest neighbour distribution which had worked
out very well in accordance theoretical predictions.

Apllication of covariance/correlance analysis turned out to be useless,
because this investigates a search into linear dependencies of the x, y, z
vectors and this is not of interest.

Now, with the numbers generated below, the spatial coordination index
looking for clusters and holes in 3d space should come out near zero.
Somebody trying to run the numbers?

Subject: [Scilab-users] graphics .uid : usage (& display)
Message-ID: <0fc4c02f-b09d-fa49-9d3e-7849d3f40a31@free.fr>

Dear co-scilabers,

I am wondering about the hidden "uid" property of all graphical objects :
--> plot()
--> gcf().uid
  ans  =
    581.
--> gca().uid
  ans  =
    628.
--> gce().uid
  ans  =
    675.

It is a protected property, and it's OK:
--> gca().uid=500
Unknown property: uid.

*Question #1*: this property is not displayed. Is it on purpose?

*Question #2*: What can we do with this property? In particular, can we 
call directly some java routines with it, and then: How (example)?

I was digging around this uid, because i am searching for a robust -- 
and if possible built-in -- way to declare that a graphical component 
relies on another one. Examples :

  * a label of a contour line is "ascribed" to this line
  * a colorbar (that is an axes in its own) is related to a given other axes
  * etc.

Of course, it is possible to use the .tag property of the "parent" 
object (the line, the colored axes,..), and register it in the .userdata 
property of the "child" (the label, the colorbar..). And may be i will 
finally do things in this way.

But since there is this ".uid" that has the main advantage to be unique, 
with which we are sure that there was no id collision, i was wondering 
about it.

 From here to there, i was wondering about the robustness of these uid 
values when saving in a file a figure or a graphical component, and then 
reloading it 2 months later. It comes that .uid values ascribed to the 
reloaded objects are NOT the original ones. So, unfortunately, referring 
to uid to link objects is not robust...

So, if anyone knows

  * something about questions #1 and #2
  * how to avoid using the .tag to declare robust links between
    graphical objects

Hope reading you.

Best regards
Samuel

Hello,
is there a function available to shift indices?
E.g. I have

and want
bb =  6.   7.   8.   9.   10.   1.   2.   3.   4.   5.


If you need to shift i = 1:n indices by any p -- not necessarily n/2 --, you
may do

si = modulo(i+p-1, n)+1    // with n = length(i);

Example:
i = 1:10, p = 2;
si = modulo(i+p-1, length(i))+1
--> i = 1:10, p = 2;
 i  = 
   1.   2.   3.   4.   5.   6.   7.   8.   9.   10.

--> si = modulo(i+p-1, length(i))+1
 si  =

Done here: http://bugzilla.scilab.org/15035

All regressions -- especially coming from Scilab 5.4.0 up to now, but 
even before -- would be excellent targets for the GSOC 2018.
I have started making a list of them. I will put it on the Wiki.

It is somewhat vain to add new features to Scilab if useful or even 
mandatory existing ones are slowly but surely getting eroded, sometimes 
in a blocking way.

	(SEP)
Message-ID: <9db4d179-650e-6678-f3b5-2607cb1ff053@free.fr>

Dear co-users,

New smart lines styles #7 to #10 were defined 3-4 years ago:
https://help.scilab.org/docs/6.0.0/fr_FR/polyline_properties_3.png

However, the default grid_style == #3 has not been improved.
Being aware that better styles are available, this makes me setting by
hand the grid_style almost every time that i need it. Somewhat boring...

I propose to change the default style to one of the new values #7 to #9.
The full rational for this proposal is posted as bug 
http://bugzilla.scilab.org/15421
where a piece of code is available, to test and compare.

The related screen shot is here:

So may be it's a RAM issue. If you need a lot of intermediate memory and 
you don't have it (here you need 2GB per copy, if you are using decimal 
numbers), it usually goes to the disk space.. which is unbearably slow.

My two cents..

Hello,

A priori, there is no reason why your calculation should use more than 
one CPU core, which explains why you see only 1/8=12,5% CPU use.

Hello,


If your problem is embarrassingly parallel (ie you run your simulations 
many times independently for different random matrices), you might speed 
up the overall simulation by running more than one instance of scilab in 
parallel.

Dear Mottellet

But there is an explanation "If we use the Intel MKL on Windows, then Scilab
use all the cores available on the processor. "
https://wiki.scilab.org/Documentation/ParallelComputingInScilab

So I expected there are some ways to increase the usage of cpu.

  If your program does not take advantage of the MKL Intel library, it  
means that its CPU usage is not dominated by linear algebra stuff. If  
you don't tell us more we won't be able to help...

I was actually wondering that the bootle neck is not the CPU. This is 
why i was thinking about the RAM.
But with 64 GB, this means that more than <32 copies are simultaneously 
defined/reserved (internally and/or in the Scilab program).
Fujimoto2005, couldn't it be the case, in your Scilab code?
Are you cleaning properly all intermediate variables after usage?

Samuel

Dear all
Thak for your replies.

I attach my code and snapshot of task manager.
corSmplebaseZ1andZ2.sce
<http://mailinglists.scilab.org/file/t497065/corSmplebaseZ1andZ2.sce>  
snapshot_of_task_manager.png
<http://mailinglists.scilab.org/file/t497065/snapshot_of_task_manager.png>  

The snapshot shows typical situation.
The CPU usage is usually between 10% and 20%.
There are 3 or 4 times when the utilization rate instantaneously reaches
between 40% and 50%.
Memory usage does not exceed 20 GB. There is always at least 40 GB of free
memory.

Best ragards

Hello,

In your code, most of the cpu time is spent between lines 40-54 (random 
generation of big matrices), then between lines 54-60, where one of the 
bottlenecks is the use of repmat (and you use it twice) and the 
"cumsum".In previous posts of Heinz Nabielek related to code 
optimization, you may have noticed that using matrix multiplication by a 
vector of ones gives the same result BUT uses the BLAS ! For example, 
compare these timings, with size(timePoints_V)=[1 25000] and sample=5000) :

tic;repmat(timePoints_V,2*sample,1);disp(toc())

 ?? 12.372273

tic;ones(2*sample,1)*timePoints_V;disp(toc())

 ?? 1.823105

On my machine (MacPro, OSX, Scilab 6.0.0), this last piece of code uses 
100% cpu (four cores).

S.

Hi,
I'm still having trouble to use scilab 6.0.0 in Ubuntu 17.10. As i stated in previous mail, i managed ton install ubuntu 18.04 version, but it has the well known input function bug. I can live without input, despite i use scilab for teaching numerical methods and input is very useful. But then i realized atoms is also not working, at least in my pc. I get the error

So, i thought i could compile scilab myself, but when running configure file, i get this error:

configure: error: curl : library missing. (Cannot find symbol curl_easy_setopt). Check if curl is installed and if the version is correct

Curl is installed:

curl -V
curl 7.55.1 (x86_64-pc-linux-gnu) libcurl/7.55.1 OpenSSL/1.0.2g zlib/1.2.11 libidn2/2.0.2 libpsl/0.18.0 (+libidn2/2.0.2) librtmp/2.3

So i wen to config.log and found this:

I have libssl and libcrypto, but i think i have newer versions. I could not manage to install those versions.

Is this the problem? how can i solve this?
Thanks

Thanks,
I solved it updating too. Anyway, that version is the one with input command bugged. I wish i could use a nigthly build where that bug is fixed. Also, trying to download a nigthly build lead me to 404 http error.

Hi, I also followed the steps in my Ubuntu 17.10 but it just keeps installing scilab 5.5.2. Am i doing something wrong?
I seem to remember doing a "sudo apt update" after step 2, before step 3. I also made sure I had removed the 5.5.2 release before trying this, just to make sure things didn't get confused. Though as shown in my last message I still managed to confuse myself a little bit by not removing the tarfile 6.0.0 release I had lying around :-) Hope this helps, Paul _______________________________________________ users mailing list users at lists.scilab.org<mailto:users at lists.scilab.org> http://lists.scilab.org/mailman/listinfo/users

Sorry, this is the error i'm having with atoms:

        No ATOMS module is available. Please, check your Internet connection or make sure that your OS is compatible with ATOMS.

If i do atomsSystemUpdate() i get:

Scanning repository http://atoms.scilab.org/6.0 ... Done at line 265 of function atomsDESCRIPTIONget ( /usr/share/scilab/modules/atoms/macros/atoms_internals/atomsDESCRIPTIONget.sci line 284 ) at line 16 of function atomsSystemUpdate ( /usr/share/scilab/modules/atoms/macros/atomsSystemUpdate.sci line 33 ) atomsDESCRIPTIONget: save ('/home/pablo/.Scilab/scilab-6.0.0/.atoms/packages') has failed.

Thanks

Hi,
I'm still having trouble to use scilab 6.0.0 in Ubuntu 17.10. As i stated in previous mail, i managed ton install ubuntu 18.04 version, but it has the well known input function bug. I can live without input, despite i use scilab for teaching numerical methods and input is very useful. But then i realized atoms is also not working, at least in my pc. I get the error

So, i thought i could compile scilab myself, but when running configure file, i get this error:

configure: error: curl : library missing. (Cannot find symbol curl_easy_setopt). Check if curl is installed and if the version is correct

Curl is installed:

curl -V

So i wen to config.log and found this:

I have libssl and libcrypto, but i think i have newer versions. I could not manage to install those versions.

Is this the problem? how can i solve this?
Thanks

Thanks,
I solved it updating too. Anyway, that version is the one with input command bugged. I wish i could use a nigthly build where that bug is fixed. Also, trying to download a nigthly build lead me to 404 http error.

I seem to remember doing a "sudo apt update" after step 2, before step 3. I also made sure I had removed the 5.5.2 release before trying this, just to make sure things didn't get confused. Though as shown in my last message I still managed to confuse myself a little bit by not removing the tarfile 6.0.0 release I had lying around :-) Hope this helps, Paul _______________________________________________ users mailing list users at lists.scilab.org<mailto:users at lists.scilab.org> http://lists.scilab.org/mailman/listinfo/users

Subject: [Scilab-users] How to change/update XCOS block
Message-ID: <1518600193567-0.post@n3.nabble.com>

Hi everyone,
I have few XCOS schemes with a custom block inside. 
Then I changed block definition by changing some properties.
Is there any way to replace that block in scheme without manual 
interference by using some kind of existing tool? 

e.g 'magicFunctionToUpdateBlocks('sample.zcos');'

Regards, 
Lukas

Dear Mottelet 
Thank you for your useful advice.

1, By changing repmat(timePoints_V,2*sample,1) to
timePoints_M=ones(2*sample,1)*timePoints_V and using it, calculation time is
improved by 25 seconds.

2, "cumsum" is not a bottleneck because it takes only 2 seconds to finish.
Also, if I change cumsum(wY1_M,'c') to linear algebra version
wY1_M*triu(ones(time_step,time_step)), calculation time increases to 2
minutes although CPU usage rate rose greatly. "cumsum" function seems
efficient function.

3, Is there any way to improve random number matrices generation? The
attached file is a snapshot of the task manager when generating random
matrices. It shows the CPU utilization remains low despite using many slots.
What is the cause?
snapshot_of_task_manager2.png
<http://mailinglists.scilab.org/file/t497065/snapshot_of_task_manager2.png>  

4, If I can generate multiple random matrices with smaller row size at the
same time and integrate them at the end, I expect the processing time will
be shorter, but can not  I do such a thing?

Best regards.

Thank you St?phane for having pointed out the repmat() slowness.

Additional tests show that the Kronecker product is even slightly faster 
than .*

A new version of repmat() is proposed on review: 
https://codereview.scilab.org/19782
It is rewritten mainly using .*., which simplifies a lot the code.

This version is more than 7x faster than the current one, and uses both 
CPU of my PC.
It is roughly the ratio 12.37/1.82 ~ 6.8 that you give here-above.

Best regards
Samuel

Hello Samuel,

It is a good initiative. Looking at your proposed code, I see that you 
use "execstr" on strings which are forged on the fly. Although the 
obtained expression will be faster (this was the goal), AFAIK such 
constructs are not "compilable" the same way as the straight expression. 
For the time being, Scilab does not use JIT compilation, but I think 
that such  constructs are typically not optimal and that it/then/else 
constructs should be used instead.

S.

Hello Amit,

It would be nice to have a machine learning however you could start by taking a look at what's
already exists in http://atoms.scilab.org and on http://scilab.io/category/machine-learning . Could
you try to improve what's already existing ?

Thanks,

Hi? Amit,

Greeting. I am Chin Luh, the author for Neural Network module in atoms 
portal (https://atoms.scilab.org/toolboxes/neuralnetwork/2.0). Thlde 
module is base on the book "Neural Network Design" by Hagan Martin (1st 
version) and the codes are following the pseudo code given in the book.

If you are interested, you could look into this module and implement the 
"Regularization" into the algorithms for all the FFBP? in the module, 
which is highlighted in one of the session in Andrew Ng's? machine 
learning course.

One thing you might need to be careful: In Machine Learning Course you 
attended, Prof Andrew using the notation where the training dataset 
arranged in rows, and the features arranged in columns. This is the 
reverse with this module, the book this module referred to, as well as 
the standard way python used. However, In Prof Andrew first course in 
Deep Learning specialization, he used the same notation with this module.

As this module is totally in Scilab code, I personally believe that it 
is easy to start.

Just my 2 cents, hope this helps.

Thanks.

Regards,
Chin Luh

Dear Scilab users,

We are very happy to announce the release of Scilab 6.0.0.

The Scilab Team invested significant development efforts for the past years in order to release Scilab 6.
The goal with Scilab 6 is to address technological evolutions and new needs in terms of modeling and simulation from the scientific & engineering community.
This led our team to completely redevelop the computation core of Scilab in order to build a solid base combining performance and evolutivity.
The new aspects of Scilab 6 worth notifying are the following:

*	New language parser & new core,
*	New utilities for development productivity,
*	Xcos block diagram improvement,
*	Newsfeed - a communication channel with the users 

Download it on Scilab.org <http://www.scilab.org/> 

Scientifically yours

Hi,
As far as i know, scilab asks for your information after the download has started. At least, that's my case. Perhaps your browser is blocking the download?

Hello,

Scilab 6.0.0 and 6.0.1 (and the master branch) cannot be build using 
OCaml 4.06 because this release remove the Num library 
(https://ocaml.org/releases/4.06.html#Changes,

build Scilab with recent OCaml: integrate Num in Scilab, build Num

Thanks by advance,

Message-ID: <b59644b5-5522-b0a5-1b4f-e3d0e7cfaea5@laas.fr>

Hi all,


I am a bit surprised by the way isoview acts on a surf plot.
It seems to just scale the x,y,z axis so that the plot is inside an 
isometric 3D cube.
I was expecting an aspect ratio that depends on the Z matrix value and 
size or on the X,Y coordinate vectors and the Z matrix value.
Here is an example:

//without X,Y axis: expecting an aspect ratio in the (x,y) plan 
corresponding to the dimensions of the Z matrix
Z=rand(10,30);
h=scf();
surf(Z);
isoview("on");//we should see a 3/1 aspect ratio in the x/Y plane but we 
have square

//trying with X,Y coordinates: expecting an the plot to fit inside a 
"cube" with aspect ratios along the x,y & z directions
//that depends on max(X)-min(X), max(Y)-min(Y) & max(Z)-min(Z)
Z=rand(10,30);
X=1:size(Z,2);
Y=1:size(Z,1);
h=scf();
surf(X,Y,Z);
isoview("on");//we should see a 3/1 aspect ratio in the x/Y plane but we 
have square


Am I the only one to expect this behaviour?


Antoine

OK, answering my own question:

It seems that when calling surf(), the cube_scaling property of the 
current axis is set to "on", which results in the observed behaviour.
Manually resetting to its default value "off", gives me the expected 
behaviour.
Should I fill a bug about the absence of cube_scaling mention on the 
help pages of surf() and isoview() ?

Hello Florian,

The easier would be to depend on the external Num library for the 6.0.x family as far as this
library remains available; statically build against it is the way to go for OCaml code. Num might
also be packaged in your system, use ocamlfind to look for it.

Thanks,

Hello,

The cube_scaling appeared with version 5.2 or 5.3 (I don't remember) 
because the previous default behavior, which corresponds to

cube_scaling="off"

could produce surfaces which were very hard to visualize with default 
angles and hard to homogeneously "rotate" in the elevation angle, when 
the surface is very flat. See this example:

clf
[x,y]=meshgrid(-1:0.1:1,-2:0.1:2);
surf(x,y,x.*y*1e-5)
gca().cube_scaling="off";

The default combination cube_scaling="on" and isoview="off" corresponds 
to the default behavior in Matlab. Introducing the cube_scaling property 
and its default value helps "migrating users" as they obtain the same 
thing in both softwares.

Anyway, I don't think that the combination cube_scaling="off" and 
isoview="off" has still an interest as it can produce the annoying 
behavior of the above example. The default combination cube_scaling="on" 
and isoview="off" allows the 3D object to fill the whole 3D box whatever 
the proportions of the enclosing 2D canvas, which is the expected 
default behavior.

Antoine's remark points out that cube_scaling="on" and isoview="on" 
produces a plot whose proportions are completely wrong with respect of 
the value of isoview="on". Adding in the help page of 
"axes_properties/isoview " a sentence such as

If you want *real* isometric scales on all axes in 3D you have to set 
cube_scaling property to 'off'

is not admissible.Setting the value of cube_scaling? to the opposite of 
the isoview value when the latter is changed could be a solution. At 
least, when the high level isoview *command* is used.

Great ! But in this case I would add also

isoview('off') missed switching .cube_scaling='on'

Hello Cl?ment,

Thanks for the answer, I installed num and changed the compilation line 
to use ocamlfind but now the compilation fails with :

ocamlfind ocamlopt -package num -I ./src/modelica_compiler -I 
./src/xml2modelica -c src/modelica_compiler/optimization.ml
File "src/modelica_compiler/optimization.ml", line 166, characters 21-22:
Error: This expression has type string but an expression was expected of 
type
 ???????? bytes

Is it link to the uodate to OCaml 4.06 ?

Hello Florian,

Please find attached a patch that fix this issue; it comes from a OCaml 4.0.4 change which
distinguish String and Bytes implementations and the unsafe-string flag.

Quoting the documentation [1]:
> OCaml strings used to be modifiable in place, for instance via the String.set and String.blit
> functions described below. This usage is deprecated and only possible when the compiler is put 
> in "unsafe-string" mode by giving the -unsafe-string command-line option

Subject: [Scilab-users] "intg" and i"ntegrate"
Message-ID: <1519305566188-0.post@n3.nabble.com>

I want to integrate a user function f(x,y1,y2) from a to b with respect to x.

1, I don't see the difference between "integrate" and "intg". I saw help
file and find "integrate" can manage multi upper limits.  Except it, I can't
find any differences between two functions. Is there a difference in the
accuracy or calculation method?
 "intg" has a fixed number of partitions. Does "integrate" increase the
number of partitions automatically until the accuracy is not improved? I do
not understand the difference with the help file.
2, I could use "intg" with "intg (a, b, list (f, y1, y2))", but I could't
use "integrate" with "integrate (list ("f", y1, y2), "x", a, b)" or
"integrate (list (f, y1, y2), "x", a, b)". What is wrong with the syntax?

Best regards

Or if I can find the scripts of the examples developed in the document.
In the reading that I do of the document I have been developing these
examples. In some cases I get the expected results and in others I do not.

Is there any other similar document !?

Gracias

Subject: [Scilab-users] Overflow convention for integer types
Message-ID: <a03fcece-9689-827b-fb2c-884b9df98da6@utc.fr>

Hello,

I would like to point out the conventions used by Scilab and Matlab when 
an integer number is subject to overflow:

Scilab 6.0.1:

--> uint8(255)+1
 ?ans? =

 ? 0

Matlab R2017b

 >> uint8(255)+1

ans =

 ? uint8

 ?? 255

Do you see any reason in favor of one of each ?

S.

Maybe monotonicity, but it should be discussed anyway.

This has been already done here or/and on Bugzilla, quite extensively.

Anyway, it can't be changed without breaking completely Scilab and 
external modules.
It is the same for 1.2 * int8(3) that yields an int8 and not a double.

The fact that all these optimizations with a global impact were not 
discussed and decided
to prepare the 6.0.0 is indeed a HUGE pity.
There are many ways to kill a software. Breaking things with a global 
impact like this []+num again,
and next minor release again, and next minor release again on another 
point... is an excellent one.

So, sorry, but this kind of (re)discussion and changes must be done when 
targeting a major release
for which all things must be rewritten.
And decided and announced to all authors ASAP, not just 1 year before 
the release.

And since you put this on the table while the 6.0.1 is just released and 
we had not the chance
to read you here about that before looks rather strange to me.

Best regards
Samuel

No strangeness at all. I was just *asking* why Scilab's behavior is the 
one observed. No judgement at all, no claim. Because of a recent change 
in my professionnal position I have now enough time to spent a bit of it 
about Scilab (many years ago I spent *a lot* of time about it). Sorry 
for my "fresh" view of some facts that were discussed a long time ago, 
when I did not have time to read the mailing lists...

Thank you,

I loaded IPCV.

When I tried to execute a program from a gui screen, scilab 6.01 stopped working.

I will have to see whats wrong.

Hi guys,

I think I finally solved the problem here.

The steps that worked for me:
1) Uninstall Scilab 6.0 completely using Revo Uninstaller. Standard
uninstallation plus deleting files left that were  found by Revo.
2) Restart computer.
3) Clean full installation of the latest Scilab 6.0.1.

Done! Scilab is working again!

Best regards.

Here, an if/then/else or rather select/case construct is not possible, 
since the number of cases is unknown, open, not limited. So the 
construct would anyway include a final /else/ including an /execstr() 
/instruction.

But, even if avoiding execstr() is not a priority, there is here another 
solution, that is now implemented.

The final execstr() for the overloading routing can't be avoided. This 
is typically the case of the processing of open unknown cases.

No, since integrate() actually calls intg() to proceed. integrate() is a

Its algorithm is adaptative. The partition is dynamically refined when

Yes, since intg() does it and is called by integrate().

You are right. This

integrate (list (f, y1, y2), "x", a, b)

syntax could be added. But it is possible to use "local" parameters, 
like this:

a = 3;
x1 = 0:0.1:2*%pi;
X = integrate('sin(a*x)', 'x', 0, x1);
// Checking
norm((1-cos(a*x1))/a -X)

--> norm((1-cos(a*x1))/a -X)
  ans  =
    2.491D-15

The only thing is that the name of "local" parameters must not collide 
an internal parameter of integrate:
--> edit integrate

The list() feature specific to intg() could be included into 
integrate().  Then intg() could be undocumented as an internal function 
of integrate(). If you agree and wish such a merge, would you mind 
filling in a wish report on Bugzilla?

Best regards
Samuel

Subject: [Scilab-users] uicontrol tab
Message-ID: <1519658440146-0.post@n3.nabble.com>

I'm trying to incorporate the 'tab' function in a GUI but I don't see any tab
control when I execute the code. I can't find a tutorial for this either.
can someone please give me an example of how this is done. My code is below:

<code>
f=figure('figure_position',[400,50],'figure_size',[859,752],'auto_resize','on','background',[33],'figure_name','VISA
Interface number %d',...
'dockable','off','infobar_visible','off','toolbar_visible','off','menubar_visible','on','default_axes','on','visible','off');
//////////
handles.dummy = 0;

handles.tabframe = uicontrol
(f,'Style','tab','Position',[0.05625,0.0541667,0.7921875,0.8729167],'Visible','on','String','tab1');
</code>

I also have button controls but they work OK.

TIA James

handles.dummy = 0;

Hello Antoine
That code was originally created by guibuilder. I will change it because I
don't find that to be very intuitive, thank you.

Hello Stephane
The example code works, thank you.

Hello there, i searched in scilab a macro, that can solve me this in an 
elegantly matrix way?

I've really searched something similar to A*X=0, but no linsolver gave me 
the right answer?

Dear All, 

White background involves eye fatigue (for me at least) and I'm
wondering if a "dark theme" exists .. I had a look in scinote - maybe
I'm missing something (of course one can change the color in sconotre
preferences, but it's not convinient in my mind). 

Thanks

not really in this case, here you have already the eigenvalues lambda1=7 
and lambda2=3.
Now for lambda1, insert the number to the matrix, where sigmaxx =-1, 
sigmayy =5 and tauxy=4 already known is, as a stress tensor
 you will get two linear equation like

-8*v1x+4*v1x=0
4*v1x-2*v1y=0

normaly an trivial solution, but non of the sovers gave me the correct 
answer?

A=[-8 4 ; 4 -2]

b = [0 ; 0]

[x0, kerA] = linsolve(A, b)
 kerA  =

   0.4472136
   0.8944272

 x0  =

   0.
   0.

You notice that kerA(2)/kerA(1) = 2 which means that the result is similar to

kerA  =

   1
   2

 x0  =

   0.
   0.

Which is the excepted solution. Or?

not really when i do it with my pencil, i get to the real values directly, 
i mean i can turn it like i want till i get the right answers that i need, 
try it with lambda2?

imean it could work but is it mathematical correct?

There is no "real" value as they are defined up to a factor.
[0.4472136 ; 0.8944272] is as correct as [2 ; 4], [0.5 ; 1] ou [? ; 2?].

Scilab performs numerical resolutions.
What you would like is symbolic resolution.
You might have a look at other softwares such as Maxima for this stuff.

So, file exchange doesn't work so i try this way.

So this is my attempt for the Mohrscher Spannungskreis.

Please impruve the code.

Well, first improvement would be to comment your code,
especially if you want other people to read it :-)

Apart from this, here are a few things:
You create a matrix called Tensor but you barely use it as a matrix;
sometimes you use elements of it, e.g. Tensor(1,1),
sometimes you use the values with their original name, e.g. Sigmaxx.
This has probably no influence considering the memory needed and calculation time
but some consistency would not hurt.

When you compute several times the same value, you should create a variable for it, e.g.

cdS = cosd(Schnittwinkel)

sdS = sind(Schnittwinkel)

TKomponenten= Schnittspannungsvektor*[cdS ; sdS]

TKoordinatenkomponenten=[cdS, sdS ; -sdS, cdS]*TKomponenten

Foo = 2*Tauxy/(Sigmaxx - Sigmayy)

aFoo = 0.5*atand(foo)

bFoo = 0.5*atand(-foo)

Richtungen1 = [0, 90, 180] + aFoo*[1, 1, 1]

Richtungen2 = [0, 90, 180] + bFoo*[1, 1, 1]

Hope this helps

sometimes you use elements of it, e.g. Tensor(1,1),
sometimes you use the values with their original name, e.g. Sigmaxx.
This has probably no influence considering the memory needed and 
calculation time
but some consistency would not hurt.

When you compute several times the same value, you should create a 
variable for it, e.g.

cdS = cosd(Schnittwinkel)

sdS = sind(Schnittwinkel)

TKomponenten= Schnittspannungsvektor*[cdS ; sdS]

TKoordinatenkomponenten=[cdS, sdS ; -sdS, cdS]*TKomponenten

Foo = 2*Tauxy/(Sigmaxx - Sigmayy)

aFoo = 0.5*atand(foo)

bFoo = 0.5*atand(-foo)

Richtungen1 = [0, 90, 180] + aFoo*[1, 1, 1]

Richtungen2 = [0, 90, 180] + bFoo*[1, 1, 1]

Hope this helps

Subject: [Scilab-users] Scilab and hdf5 format (small survey)
Message-ID: <573b912f84c6c7c8b7f73879f4e2c34e@free.fr>

Hi All  

I'm playing with hdf5 format into Scilab (I'm currently in an early
stage that consists in understanding what the structures are); the goal
is to deal with huge amount of data coming from Finite Element Analyses,
and to perform additional calculations. 

I'm wondering if there are a lot of people working with Hdf5 file into
Scilab? in what fields? 

(behind this, a goal among others  is to get feedbacks from them on
advantages and disadvantages). 

Regards 

Paul

Hello,

With the new library system, it is no longer possible to clone a 
function in a library. This feature is still documented in the help page 
of "lib" but is not working anymore since saving a user-defined scilab 
function uses the sod/hdf5 format. Maybe one can ask why such a feature 
is needed ? Sometimes it can be usefull to have a function which is 
callable by different names but actually does the same thing. The 
different calling names can come from the adaptation for different types 
of data, which can sometimes lead to the same treatment, hence to the 
same function. Instead of writing two functions with the same source 
code but a different calling name, cloning the original one was an 
interesting feature.

I admit that the way it worked under scilab<6.x was not clean at all 
*but* officially documented in the "lib" help page. For example, imagine 
that a library has just been built (e.g. the plotlib...)

genlib('plotlib','macros')

I need to add to this library %axesData_i_h which is a clone of 
generic_i_h (in overloadinglib), which can be done in scilab<6.x by:

%axesData_i_h=generic_i_h;
save('macros/%axesData_i_h.bin',%axesData_i_h)
mputl([mgetl('macros/names');'%axesData_i_h'],'macros/names')

I said above "not clean at all", because the binary file "macros/lib" 
(which is created by the genlib call) does not need to be updated, as a 
subsequent

plotlib=lib("macros")

loads all functions, including %axesData_i_h


Doing things like this is not possible any more. It was was also to add 
persistent variables in libraries, with the same mechanism.

By the way, under scilab 6.0.1, the "macros/lib" is now an XML file with 
a clear syntax, e.g.

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<scilablib name="plotliblib">
 ? <macro name="%c_i_pltlibH" file="%c_i_pltlibH.bin" 
md5="d0966468b335a69681a29d84c99feb5c"/>
 ? <macro name="%figureDa_i_h" file="%figureDa_i_h.bin" 
md5="a1ebda57a1607b28095def2e415e2ec1"/>
...
</scilablib>

It does not seem to be documented either.

S.

Hello St?phane,

I would try the following:
After genlibing the set of regular .sci files,
* save the clone with
    save('macros/%axesData_i_h.bin', "%axesData_i_h")
* add a line in the lib file

<macro  name="%axesData_i_h"  file="%axesData_i_h.bin"  md5="e833d190e21b93af335a011ea9e76aef"/>

The MD5 hash is of the content of the .sci file, that here does not 
exist. It is use by genlib to check whether the .sci must be recompiled 
or not. You may try to set any md5 (or the cloned one). As long as you 
don't recompile the lib with genlib -- just loading it with load() or 
lib() --, this should work.

My 2 cents..

Samuel

Another way would be to clone the source file with a hard link with your OS.
It is possible with Linux. It should be possible with powershell under 
Windows.
With MacOS, i don't know. Likely possible as well. Could you confirm?
Then, try genlib() and see if it considers such a link..
In Linux, it should : all inodes are equal
In Windows: I will try, when updating the lib() and genlib() pages

But it should be portable. I don't think that hard links are so..
As long as the library is not recompiled by the user, it should work.
Otherwise, hard links should be set in the module builder, before 
building the library, and according to the OS...

Thanks Samuel, the problem is that

save('macros/%axesData_i_h.bin', '%axesData_i_h')

will produce a .sod file with a .bin extension. Both formats cannot be 
used indifferently for compiled macros of a library : in the following 
code (that can be copy/pasted), a library is built, the "fun1" function 
is saved in sod format, then the reference to "fun1.bin" is replaced by 
"fun1.sod" in the lib file :

path=TMPDIR+'/test/';
mkdir(path)
mputl('function y=fun1(x), y=x, end',path+'fun1.sci');
genlib('test',path)
save(path+'fun1.sod','fun1')
doc=xmlRead(path+'lib');
doc.root.children(1).attributes.file='fun1.sod';
disp(xmlDump(doc))
xmlWrite(doc,path+'lib');
clear
lib(TMPDIR+'/test/')

The following output is obtained:

!<?xml version="1.0" encoding="UTF-8" 
standalone="no"?>???????????????????????? !
! !
!<scilablib name="test"> !
! !
!? <macro name="fun1" file="fun1.sod"

! !
!</scilablib> !

Emplacement des fichiers des fonctions : /.

fun1

Unfortunately, calling fun1 crashes scilab...

:

When on Windows making a *symbolic link*
--> host("mklink test2.sci test1.sci")  // mklink  copy source

and then running genlib (=> no complain), genlib yields the following 
lib file:

<?xml  version="1.0"  encoding="UTF-8"  standalone="no"?>

!
Then, running fun2(1) crashes Scilab (at least this unstability is... 
constant ;)
Let's try making and using a hard link...

If in the file /myfun.sci/ genlib() does not find any function named 
"myfun",
then genlib ignores it and add no entry to the lib file.

Unless bypassing genlib(), this somewhat prevents using soft or hard 
links for the targeted purpose...

Last trial for today:

  * Define fun1() in fun1.sci.
  * Compile fun1.sci with genlib(): OK => fun1.bin available
  * Create fun2.bin as a hard link to fun1.bin:
    host("mklink /H fun2.bin fun1.bin")  // Windows
  * Update (by hand or code, not with genlib) the lib file:

    <?xml  version="1.0"  encoding="UTF-8"  standalone="no"?>
    <scilablib  name="testlib">
       <macro  name="fun1"  file="fun1.bin"  md5="8a3737878c543f1a5005c42122236628"/>
       <macro  name="fun2"  file="fun2.bin"  md5="8a3737878c543f1a5005c42122236628"/>
    </scilablib>

  * load the library (OK : both fun1 and fun2 are loaded):
    --> lib ./
      ans  =
    Functions files location : TMPDIR\test.
    fun1  fun2

  * fun1(1)   //=> OK
  * fun2(1)    // .... => crash

A bad end.
It is likeky vain to go on fighting without Antoine Elias advices and

Already tried this one with fun2.bin as a copy of fun1.bin. I noticed 
that under scilab 5.5.2,

  * Define fun1()
  * fun2=fun1
  * save("fun1.bin",fun1)
  * save('fun2.bin',fun2)

gives a fun2.bin different from fun1.bin as the string "fun1" appears in 
fun1.bin and "fun2" appears in fun2.bin

Message-ID: <c14f07c046623c5a9fca2bfebb49cdbf@free.fr>

Hi 

In the following example, I'm digging into the Scilab help pages in
order to understand how I can use hdf5 format; nevertheless I'm still
wondering how I can have access to the sub-structure (sub-groups and
datasets on them) ? 

(I'm thinking in programming recursive search ...) 

Thanks 

Paul

PATH = get_absolute_file_path("test_hdf5.sce");

// the new file is created
a = h5open(PATH + "/tests.h5", "w");

// a basic group is created
group_name = "MyGroup";
h5group(a, group_name);

// sub-groups creation (using a loop)
for i = 1 : 10
    s = group_name + "/sub_group" + string(i);
    h5group(a,s)
end

// specific groups & sub-groups
h5group(a, "FEM");
h5group(a, "FEM/NODES");
h5group(a, "FEM/ELEMENTS");

// dataset creation using a data matrix
n = 1E3;
i = (1:n)';
A = rand(n,3);
Nodes = zeros(n,4);
Nodes(:,1) = i;
Nodes(:,2:4) = A;
h5write(a,"NODES",Nodes'); // dataset name is NODES here - do not
confuse with the sub-group
h5write(a,"FEM/NODES2",Nodes'); // dataset name is NODE2 in FEM group
h5write(a,"FEM/NODES/new_nodes",Nodes'); // add of a new dataset names
"new_nodes" in the subgroup NODES in FEM

// tests on the contect of the file (see H objects)
// it's expected to find sub-groups and dataset into them
a.root // list of the groups / datasets and so on at the root
a.root.datasets // specifically list of the datasets

a.root.NODES // provides information's of the "NODES" dataset

Subject: [Scilab-users] int2d
Message-ID: <1519856231321-0.post@n3.nabble.com>

In order to calculate the expected value of a certain two-variable function,
I have created a density function of two-dimensional normal distribution.
I created a code like the attached file to check the correctness of the
function, but it does not work.
Where is the code wrong?

I have been confirmed int2D supports list format for a function call.
Furthermore running the code doesn't show "called multNormDensFunc1".
This means it fails to call "multNormDensFunc" function.
 
Best regards.
