Dear Phililip!

I do not know about MS compiler.
I use GCC from mingw on my Windows 8.1 laptop.

I installed version 0.9.3 from ATOMS
<http://atoms.scilab.org/toolboxes/mingw/0.9.3>:
1. installed gcc x64 from -
http://atoms.scilab.org/toolboxes/mingw/0.9.3/files/gcc-4.6.3-64.exe
2. logged out
3. installed mingw toolbox in Scilab with
atomsInstall('mingw');
4. restarted Scilab
5. tested mingw toolbox with
atomsTest('mingw');

Hope this helps.

Hi,

If I understand correctly, you would like to create the filter in 
Scilab, and directly access from Xcos?
if so, u could use the syslin object to do so.

1. Create the syslin obj
h1 = wfir("lp",2,[.2 0],"re",[0 0])
h2 = wfir("hp",3,[.1 0],"re",[0 0])
num1 = poly(h1,'z','coeff')
d = ones(1,size(h1,2)+1)
d(1:$-1) = 0
den1 = poly(d,'z','coeff')
H1 = syslin('d',num1,den1)
num2 = poly(h2,'z','coeff')
d = ones(1,size(h2,2)+1)
d(1:$-1) = 0
den2 = poly(d,'z','coeff')
H2 = syslin('d',num2,den2)

2. In Xcos
use H1.num in the numerator block for LPF, H1.den in the denominator for 
the LPF, same for the HPF.

Hope this helps.

rgds,
CL

This most recent testimonial lengthens the already long list of similar 
posted issues.

The Scilab Preferences system is available since Scilab 5.4.0, so for 
almost 5 years.
It is somewhat hard to understand why compilers are not explicitly set 
in the Preferences,
instead of using a labyrinthine system of internal macros hard to 
maintain to /try/ to
detect installed compilers.

This wish for simplifying and making Scilab more reliable and simple to 
use with compilers
is reported @ http://bugzilla.scilab.org/12355

Implementing this in Preferences, and replacing calls to automatic 
detection with
Preferences settings in Scilab macros, could be a priority for Scilab 6.1

Best regards
Samuel Gougeon

Hi 

I've been thinking that Scilab uses the closest zlev than the one I'm
specifying, based on the points I provided ... am I correct? 

I've to find a way to create the points I need with z=0 ....

Hello,

You are setting an inappropriate mode in flag.

Subject: [Scilab-users] Fundamental problem with "histc"
In-Reply-To: <1491049605793-4036096.post@n3.nabble.com>
References: <1491049605793-4036096.post@n3.nabble.com>

Found out myself: Scilab help pages say

histc
computes an histogram
Description
This function computes a histogram of the data vector using the classes x.
When the number n of classes is provided instead of x, the classes are
chosen equally spaced and x(1) = min(data) < x(2) = x(1) + dx < ... < x(n+1)
= max(data) with dx = (x(n+1)-x(1))/n.
The classes are defined by C1 = [x(1), x(2)] and Ci = ( x(i), x(i+1)] for i
>= 2.

For me, this is the wrong definition, because it throws all zeros and ones
into one bin. However, I am not suggesting a change in Scilab [but perhaps a
warning against misunderstandings] and instead of

histc(0:10, A, normalization=%f) ;

I use now

histc(-0.5:9.5, A, normalization=%f).

That solves my problem.

Heinz

Hi Samuel 

Even when using mode = 1 (as the other in fact) in the flag,  the result
remains identical 

_Nb_: I probably pasted the latest trial I did :-) 

Paul 

// flag=[mode,type,box]
// mode : //string representation mode.
       //mode=0: the level curves are drawn on the surface defined by
(x,y,z).
       //mode=1: the level curves are drawn on a 3D plot and on the plan
defined by the equation z=zlev.
       //mode=2: the level curves are drawn on a 2D plot.

//type : an integer (scaling).
       //type=0 : the plot is made using the current 3D scaling (set by
a previous call to param3d, plot3d, contour or plot3d1).
       //type=1 : rescales automatically 3d boxes with extreme aspect
ratios, the boundaries are specified by the value of the optional
argument ebox.
       //type=2 : rescales automatically 3d boxes with extreme aspect
ratios, the boundaries are computed using the given data.
       //type=3 : 3d isometric with box bounds given by optional ebox,
similarily to type=1
       //type=4 : 3d isometric bounds derived from the data, to
similarily type=2
       //type=5 : 3d expanded isometric bounds with box bounds given by
optional ebox, similarily to type=1
       //type=6 : 3d expanded isometric bounds derived from the data,
similarily to type=2

//box : an integer (frame around the plot).
       //box=0 : nothing is drawn around the plot.
       //box=1 : unimplemented (like box=0).
       //box=2 : only the axes behind the surface are drawn.
       //box=3 : a box surrounding the surface is drawn and captions are
added.
       //box=4 : a box surrounding the surface is drawn, captions and
axes are added.

//ebox : used when type in flag is 1. It specifies the boundaries of the
plot as the vector [xmin,xmax,ymin,ymax,zmin,zmax].

//zlev : real number.

Hi,

Try code below, which does not uses zlev but nz = [0,0] instead.
Attached picture is produced.
<http://mailinglists.scilab.org/file/n4036108/Contour_zero_highlighted.png> 


// START OF CODE
X = linspace(-3,3,100);
Y = linspace(-3,3,100);
Z = sin(X'*Y)-0.3; //+ X'*ones(X);

clf()
xset("colormap",jetcolormap(256));
Zc = 0;
xtitle("Z=" +string(Zc) +" contour");
colorbar(min(Z),max(Z));
a=get("current_axes");
a.x_label.text=" X";

you're welcome.
anyway it should be a better way to construct the denominator, do let me 
know if you find a better way. :)

Indeed. I was misled by the zlev option. It is just the single level of 
the plane on which contours must be plotted (instead of ?) in addition 
to on the Z(x,y) surface.
The help would deserve being clarified.

Right.
When Zc is not a strictly positive integer, it should be taken as a 
single Z level.
But it is currently not the case. It is a bug : 
http://bugzilla.scilab.org/13467

Then, for plotting the only level z=0, specifying 1e-300 would be OK
And for plotting the only level z=2, 2*(1+%eps) would do it.

Doubling [Zc Zc] is another trick. contour() does not apply unique() on 
specified levels,
and so processes the same level twice. Another improvement to implement.

Several tests of contour's zlev parameter failed to produce contours at the
request depth level.
This looks like a bug too.

Thanks Pierre and Lamy. Now I have another question:


I draw a simple function and in same pic, also draw differents points (this
data in a vector)

also I want to put a label for each point "1", "2".."12"

how can I do it in scilab?, matlab's way doesn't work in my case

thanks

    x=0:0.1:1
    y=exp((x.^4+x.^2-x+(5).^(0.5))/5)+sinh((x.^3+21*x+9)./(21*x+6))-3.0;
    plot(x,y)

    x=info // it's a vector of 12 elements
    w=exp((x.^4+x.^2-x+(5).^(0.5))/5)+sinh((x.^3+21*x+9)./(21*x+6))-3.0;
    plot(info,w,'o')

Hi,

Another way to represent filter in Xcos is to use the Discrete State-Space
 (DLSS) block. The matrices can be obtained directly from the
syslin representation of the system:

[A1 B1 C1 D1] = abcd(H1);
[A2 B2 C2 D2] = abcd(H2);

(This transformation can also be set in Xcos context)

Yours

You could use xstring or xnumb:

x=0:0.1:1;
y=exp((x.^4+x.^2-x+(5).^(0.5))/5)+sinh((x.^3+21*x+9)./(21*x+6))-3.0;
scf();
plot(x,y);

num = 1 : size(x, "*");

xnumb(x, y, num);
// or:
xstring(x, y, string(num));

// plus optionally:
a = gca();
a.data_bounds = [-0.1, -0.1; 1.1, 0.75];
a.tight_limits = "on";

Subject: [Scilab-users] How to open figure properties?
Message-ID: <1491211433.711295423.iswetfv1@frv32.fwdcdn.com>

Hi! 

After upgrading to SciLab 6.0.0 there is a problem preventing easy final preparation of plottings for publications. It is impossible to open Figure properties window. 

-->? plot([1,2],[3,4]) 

--> //Now trying to open the "Figure properties" dialog using the menu of graphics window 
at line? 116 of function TK_send_handles_list ( /opt/scilab/share/scilab/modules/tclsci/macros/TK_send_handles_list.sci ????? 116 ) 
at line??? 99 of function ged????????????????? ( /opt/scilab/share/scilab/modules/graphics/macros/ged.sci ????? 110 ) 

Label not handled 

I file a bug 15102 https://bugzilla.scilab.org/show_bug.cgi?id=15102 but no activity. 

I know only one workaround - modifying the figure properties using console. It is very easy for automatic plotting preparation inside a macro but it throttles the manual preparation. 

With best regards. 
Viktor.

Thank you, Oleksiy!

I added initial state vectors to the context:
IS1 = zeros(1,length(h1));
IS2 = zeros(1,length(h2));

Now It works as expected.

Can you open "Figure properties" dialog using the graphics windows menu? 

The additional tests are performed using the following OSes: 
- Windows (Windows 10 64 bit) - the "Figure properties" dialog is openned successfully; 
- Linux (Ubuntu 14.04 64 bit) - the "Figure properties" dialog can not be openned and the error below occurs. 

at line? 116 of function TK_send_handles_list ( /opt/scilab/share/scilab/modules/tclsci/macros/TK_send_handles_list.sci ????? 116 ) 
at line??? 99 of function ged????????????????? ( /opt/scilab/share/scilab/modules/graphics/macros/ged.sci ????? 110 ) 

Label not handled 

Therefore, the problem is related to LINUX 64BIT Version (maybe, also for 32 bit). 
With best regards. 
Viktor.

I tried to investigate the problem. Running ged during the process of the dialog show cause including of the global variable ged_cur_fig_handle. It may contain the handle of the current figure. I stop the function and run 

handles = Get_handles_list(f) 
?handles? = 

37 by 1 matrix of handles: 
========================== 
Figure?? 
Axes???? 
Compound 
Polyline 
Label??? 
Label??? 
Label??? 
Label??? 
uimenu?? 
uimenu?? 
...? 
uimenu???? 

"Label" is absent in select statement of ged.sci (lines 35...117). 

Possible reason of the error - the function " TK_send_handles_list" is not fully developed in LINUX version. 

For me the following bugfix works: 

file: /opt/scilab/share/scilab/modules/tclsci/macros/TK_send_handles_list.sci 
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ 
the following code is inserted after the line 113. It may be put inside the "select? hand.type" statement before any "case" word 

??????? case "Label"????????????????????????????????? //MY BUGFIX 
??????????? iLab = iLab+1;????????????????????????? //I ASUME THAT iLab IS THE LABLE COUNTER. 
??????????????????????????????????????????????????????????????? //IF NOT, PLEASE REPLACE IT BY OTHER VARIABLE 
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? // AND INITIALIZE AT THE BEGINNING OF THE FUNCTION!!! 
??????????? Labname= "Label("+string(iLab)+")"; 
??????????? TCL_EvalStr("set "+SelObject+" "+Labname);

Hi all,

I worked further on this issue and found that it's new (unwanted) behavior
in scilab 6 since the script performs well when run under scilab 5.5.1 on
the same machine WIN7_64bits.
In scilab 6 it fails with the error message : User function 'costf' have not
been setted.

while in scilab 5.5.1: 

[fopt, xopt]=leastsq(iprint,evaloptiM1D,x0')

***** enters -qn code- (without bound cstr)
dimension=         2, epsq=  0.2220446049250313E-15, verbosity level: imp=        
2
max number of iterations allowed: iter=       100
max number of calls to costf allowed: nap=       100
------------------------------------------------
 iter num    1, nb calls=   1, f= 0.4607E+05
 iter num    2, nb calls=   3, f= 0.2185E+05
 iter num    3, nb calls=   6, f= 0.2138E+05
 iter num    4, nb calls=   7, f= 0.2130E+05
 iter num    5, nb calls=   8, f= 0.2128E+05
 iter num    6, nb calls=   9, f= 0.2128E+05
 iter num    7, nb calls=  10, f= 0.2128E+05
 iter num    8, nb calls=  11, f= 0.2128E+05
 iter num    9, nb calls=  12, f= 0.2128E+05
 iter num   10, nb calls=  13, f= 0.2128E+05
 iter num   11, nb calls=  14, f= 0.2128E+05
 iter num   11, nb calls=  22, f= 0.2128E+05
***** leaves -qn code-, gradient norm=  0.4410737793778105E-02
Fin de l'optimisation.

 xopt  =
 
    1.2213257    0.7702730  
 fopt  =
 
    21284.818  


Then I guess it's not a limitation in the algorithm itself but rather
something at the interface that has changed in scilab 6, also because the
message is issued early in the execution , about 1 s after launching the
script while the successful optimization requires at least 10-20s: probably
there's only or not even one full iteration performed before it issues
escape message in scilab 6 .
 I can't provide the detail of the function to optimize however I could
provide you with more detailed log from execution.

Regards,

David

Create a sci file (test.sci) with the following instructions (*):

It randomly makes the GUI crash. But it will not fail (according to my
tests) when executing directly (*) in the Scilab 6 GUI, without .sci

Hi Paul(s) and all,

I looked forward to the specific failures I reported for Scilab 6 for
leastsq, lsqrsolve, datafit and it looks like it is caused by fsolve call
inside my cost function while scilab 5.5 managed it well. I reported a
complete  test case
<http://bugzilla.scilab.org/attachment.cgi?id=4517&action=edit>   that shows
the bug in bug report 15117
<http://bugzilla.scilab.org/show_bug.cgi?id=15117>  . the bug 15117 tilte
mentions only lsqrsolve but it's showing also leastsq and datafit failures.

Thanks for curing the patient !

David

Hello all,

I was wondering if anyone knew how you can change the x-axis range before
the simulation runs.

What is happening is that for the cmscope, my x-axis range is only between
30 and 60. I am missing half of my data and I would like to see the full 0
to 60 range. I was wondering if anyone had any experience in this?

Hi Phillip,

On the scope, there is a "Buffer size" parameter which will define the specified period to store on
the data.

Note that during a simulation you are producing a lot of values, be sure to define it accordingly to
the period you want to observe.

Hello David,
As the documentation examples work, I can't do much of this info unless 
I get a reproducible use-case.
Maybe you could send us a minimalistic failing example?
Also, could you please fill a bug for this so we can fix it for Scilab 
6.0.1?
Thanks and regards,
Paul

Subject: [Scilab-users] Scilab 6.0.0 vs 5.2.2 - performance decrease
Message-ID: <1491561163677-4036150.post@n3.nabble.com>

Dear all,

I observed a performance decrease with relatively simple code that use a for
cycles.
bench_1.sci <http://mailinglists.scilab.org/file/n4036150/bench_1.sci>  

Almost everybody is reporting massive speed up in for cycles, but in my case
it is opposite.
In 5.2.2 run time is 10 seconds, while in 6.0.0 is 18 seconds.

Both Scilab versions are 64 bit, Win 7 64 bit.

Can somebody confirm my results?

Thanks in advance.

BR
J.K.

Hi, I ?confirm that Scilab 6.0.0 it's a bit slower than 5.5.2. It's the
time spent in the benchmark.

5.5.2
????7.151??
????7.127??
????7.123??
????7.158??
????7.169??
????7.117?
????7.154??
????7.209??
????7.117??
????7.107

6.0.0
???8.97989
???8.965782
???8.998687
???9.013485
???9.241977
???9.100208
???9.057786
???9.00625
???8.963514
???9.205469
??
I have attached some information about my CPU in this message.

DDR3
SciLab 5.5.2	-->disp(toc())		4.211

DDR2 SDRAM
			-->disp(toc())		11.384  


This was a mighty shock to me, but thanks for pointing it out.

Hi,

I want to do the equivalent of 

    plot( xdata, xdata .^ 2, xdata .^ 3, xdata '^ 4, ... );

and benefit from the plot() color rotation, without having to repeat the equation.

In Perl I might do (something like):

    plot( xdata, map xdata .^ $_, 2 .. 5 );

Something like that in SciLab?

Subject: [Scilab-users] Scilab 6, Exclamation mark in variable names
Message-ID: <58E95524.8070108@hslmg.de>

Hi,
The character "!"  in variable names is parsed as "unexpected token" and 
terminates  execution. Will this be corrected to comply with the 
documentation saying "Names of variables and functions must begin with a 
letter or one of the following special characters '|%|', '|_|', '|#|', 
'|!|', '|$|', '|?|'. Next characters may be letters or digits or any 
special character in '|_|', '|#|', '|!|', '|$|', '|?|'."?

Hundreds of my self defined functions use "!" as initial character to 
remind me that the name belongs to a function.

Kind regards
Jens

Confirmed. This is a bug. Indeed,  !a = 2  was accepted in Scilab 5.5.2.
Could you please report it on bugzilla?

Subject: [Scilab-users] Arduino ATOM on Scilab 5.5.2 under Ubuntu 16.04 LTS
Message-ID: <CADK7JfmSJA+_ZfB_grMh9RB92ysVttJnUE0eTVxY=zuOyq=8Pw@mail.gmail.com>

Dear Scilab users!

Recently I have installed Ubuntu 16.04 LTS, it has Scilab 5.5.2 in
repositories <http://packages.ubuntu.com/xenial/scilab>.

I planned to use it with Arduino Uno board, so I tried to install arduino
toolbox (ATOMS) with
-->atomsInstall('arduino')
atomsInstallList: The package arduino is not available.
 !--error 10000

at line      51 of function atomsError called by :
at line      76 of function atomsInstallList called by :
at line     233 of function atomsInstall called by :
atomsInstall('arduino')

so I can't install it.

I can't understand why this toolbox is not available
<https://atoms.scilab.org/?order=&direction=&key=arduino&title=on&platform=&scilab_supported_version=5.5>.

It has huge free-software popularization and educational potential. Isn't
it?

Someone opened ticket on Forge
<http://forge.scilab.org/index.php/p/arduino/issues/1556/> to indicate this
problem. But with no results.
It seems that Scilab-forge is half-dead.
I remember the last discussion
<http://mailinglists.scilab.org/Scilab-users-Scilab-Arduino-tt4034546.html#a4034553>
about Arduino and Scilab 5.5.2, it solves the problem, but it is not
newbie-friendly to download, extract and run ATOM-archive manually.

Please compile this toolbox for Scilab 5.5.2 and make it available as ATOM
on all platforms.
Moreover it is not available for Scilab 6 as explained in the new ticket
<http://forge.scilab.org/index.php/p/arduino/issues/1684/> and on ATOMS site
<https://atoms.scilab.org/?order=&direction=&key=arduino&title=on&platform=&scilab_supported_version=6.0>
.

Dear Paul ,

What should I do if I can't run the Modelica demos (Demos->Xcos->Electrical
systems)?

Thanks gnu

Hello Gnu,

To run Xcos demos containing Modelica (/Coselica) blocks, you need a C 
compiler, as your message title suggests.
Please refer to the compilers page 
(https://help.scilab.org/docs/6.0.0/en_US/supported_compilers.html) for 
that.

Alternatively, you may try with Scilab 5.5.2 and even report a bug 
(http://bugzilla.scilab.org) should you encounter unexpected behavior.

Hope this helps, regards,
Paul

Hello Kandy,

Are you using the Scilab 6.0.0 version or another one ? Could give more information about your
system : which OS ? hardware ?

Thanks,

PS: I suggest you to open a bug on bugzilla.scilab.org to ease communication on that issue. Users ML
 is more usage oriented.

Dear gnu!

What compiler do you use?

It is known that MinGW GCC works normally. You can install MinGW compiler
from Scilab ATOMS <http://atoms.scilab.org/toolboxes/mingw> (see its
Description).

In private, Cl?ment's rationale is, mainly and AFAIU, that preparing the 
publication of each release takes some time: There is a list of things 
to do, like formating the release notes, publishing new online help 
pages, updating download pages in several languages, etc. Then, this 
time is not used for developments.

I was asking about the intentions of the Scilab team about the future 
release frequency, because i thought -- and still think -- that roughtly 
2 years between 2 consecutive minor releases is incredibly long at the 
usual Information Technologies timescale.
Keeping such a slow rate would mean that we would have to wait up to 2 
years between the inclusion of a new feature in Scilab, and its 
distribution in an official Scilab release! So to wait even longer 
between the implementation of any new feature, and its actual 
availability in Scilab. Even for the "smallest" features, as soon as 
they are new.

Obviously, we can't ignore that each publication needs or deserves some 
specific tasks that take time, and that this time should be minimized.
Moreover, we may note that contrarily to many free and open softwares, 
nighly built releases are available online for Scilab, mostly at every 
moment. From time to time, there are some short dead periods in these 
daily releases in which the most recently included features are 
available. These binary releases can be installed and used out of the 
box like every "official" release, without uninstalling the current 
"official" release from our computer. Actually, installing a new Scilab 
version never requires uninstalling other (even multiple) versions of 
Scilab on the same computer. Everyone can have as many Scilab versions 
installed on the same computer as wished, whitout any problem. It takes 
less than 5 mn to install a new Scilab. And add some additional 5-15 mn 
to reset our Preferences, install few ATOMS modules for it, etc.
This is very great and useful and safe.

So, after our last email, i came to the following conclusion: In my 
opinion, publishing revision 6.n.X releases is useless. For the future, 
we could expect

  * The publication only of official minor versions: 6.X
    This should allow publishing them at a faster rate, at least once
    per year, never less.

  * Keeping Nightly built (daily) releases for the current 6.X+ branch,
    in which bugs are fixed "on-the-fly", the documentation is improved,
    and all other safe daily modifications are included and available on
    download the day after.

  * Keeping Nightly built (daily) releases of the master preparing the
    6.(X+1) release, in which new features or modifications that could
    make Scilab unstable are progressively included.

Hence, the publication process would take less time ; new features would 
become available in the year instead of in a 2-year period ; and 
Scilab's safety will be unchanged.

Hope reading other contributions and thoughts,

Best regards
Samuel

Subject: [Scilab-users] Cell insertion operation using {...} is buggy?!
Message-ID: <20170410141353.4c1e6917@lemon>

Hello,

Using precompiled Scilab 6.0.0 Linux 64bit, I experienced the
following:

----------------------------------------------------------------

Startup execution:
  loading initial environment
  

--> b{1}=2 // Ok
 b  = 

  [1x1 constant]


--> a=2 // Ok
 a  = 

   2.


--> a{1}=2 // Not OK, should throw an error? 
 a  = 

   1.16D-316

------------------------------------------------------------------

It seems, that the cell insertion operation via "{...}" when applied
on an existing variable does strange things.

Thanks for any advice and further insight,

Dirk

PS: Tested also with nightly build  branch-6.0-1488991653 ... with the
very same result!

Hello,

regarding future release cycles, I would really appreciate to see
offical releases as needed and based primarily upon stability criteria.

IMHO, for production use, especially after the big step from 5.x to 6.x,
it is inevitable to have official 6.0.x bug fix releases asap, otherwise
developers and users will stick to 5.5.x and get frustrated ...

Nightly builds are fine, as a testing and development platform, but not
really suited for end users ...

Regarding the incorporation of new features, it is IMHO not that
important to know, how many releases will be made per year.
It is important to know, when will a new feature be available and
useable.

In summary, I would like to see official releases as needed, rather than
following a rigid schedule.

Best regards,

Dirk

PS: Why are Coverity Fixes not directly applied to the 6.0 branch?

Hi,

My thoughts on releases. I agree that releases have been incredibly 
slow, but haven't spent time bickering about it. Instead, I'm pleased 
when releases are finally here. I've wondered about the organization(s) 
behind Scilab. It seems we get a new release every time Scilab is 
reorganized in some way ... and that there's lots of political stuff 
going on.

I hope that the Scilab 6 milestone means that Scilab (as in the software 
itself) is organized in a way suitable for the next many years. Hereby I 
imply that any 6.X release only has to reflect incremental (and 
preferably backwards compatible) improvements.

Personally I consider "nightly builds" to be bleeding edge, for 
developers, and not something I can use for my development - just as I 
cannot distribute Scilab code and reference a nightly-build version of 
Scilab to whoever might be interested.

 >each publication needs or deserves some specific tasks that take time

Yes, typically minimized by writing a developer-oriented "how-to" 
release (aka to-do list).

IMHO regarding release frequency, the second-most important reason to 
release is so that the project appears alive and not dead.

Best regards,
Claus

Wouldn't this question make more sense to be asked to the industrial partners
of Scilab?
For simple hobby users like us that freely enjoy Scilab's scientific
computing power for testing code and ideas, shouldn't the answer to the
question be correlated with the frequency of their donations?
I am sorry if I do not understand much about free software, may be it
updates itself freely too.

Hello Michael,

Even if it can be frustrating, please keep the discussion on https://bugzilla.scilab.org/show_bug.cg
i?id=14698 rather than spamming the users ML. This users ML is dedicated to community knowledge
sharing and is not a way to contact us.

AFAIK there is no workaround and it is not clearly identified as Samuel noted.

Thanks,

Message-ID: <848-58ecc500-1-2cde0300@69569739>

Hi all,

I wonder whether any of you has tried to use optimized ATLAS binary instead of the default one provided by Scilab (in the SCI/lib/thirdparty).
I read that it can greatly increase Scilab speed for some linear algebra computations (see Programming in Scilab by Micha?l Baudin, p135, available here: http://forge.scilab.org/index.php/p/docprogscilab/downloads/).
I tried to remove libblas from the SCI subfolders, but then it seems that Scilab fails to find the library installed on my machine.
Any tips?

Antoine

Dear Antoine!

On Ubuntu and Debian you can install Scilab from official repositories and
then switch libblas or liblapack to ATLAS with
update-alternatives (see
https://wiki.debian.org/DebianScience/LinearAlgebraLibraries).
Hope this helps.

Hello Nikolay,

Thanks for the tip.
Saddly, the version in the repositories are too old for me.
I assume that using update-alternatives on libblas & others will not change my problem of scilab not finding the installed libraries.
There might be a LD_LIBRARY_PATH to set somewhere....

Thanks anyway,

Antoine

Message-ID: <CAGjkK=feRrZ6S+OT5R4Q-zH0kNkZrBbzGi=3h1Y2xy4Tzv7Ffw@mail.gmail.com>

Hello all,

I have some data from a test that I preformed. I was looking to simulate
this data under different conditions and I was wondering if there is a
palette in xcos that would allow me to input data (maybe from an excel
spreadsheet or copy paste) in order to use in the simulation?

Is this possible with xcos?

"Simulate the data"?

Surely you mean you wish to simulate the system which was used in the
measurement!

You don't give much detail, but I suspect that what you want to do is
to develop a model of the system that fits the experiment, and then use
that model in your simulations.

The general term for generating the model is called "system
identification", but that covers a pretty broad swath.

Can you share the test you did, the sort of data you collected, the
sort of system you're trying to model, and how well you know the system
itself?

Hello, 


I am using Scilab 5.5.2  64bit on my windows 7 PC.

I am not sure how I can change the starting directory.
May I ask how I can change the starting directory when we start Scilab? 


Thanks.

Hi Noguchi-san

Response from Wolfgang Schulz is good. I just wish to elaborate, there 
are different settings for directories, like "home" and "SCIHOME" ... 
Please see for example: https://help.scilab.org/docs/6.0.0/en_US/home.html

Best regards,
Claus

Thanks.

However, I don't really understand what does "Menu Edit/Preferences " mean.

>From the SCilab console, I know there is SCilab setting menu. We can change color, SCinotes and Xcos settings.
However, I failed to find the place so thatI can change Home directry.

Claus-san,


My home and SCIHOME are as follows:

 home  =  C:\Users\Noguchi_Yoshikazu   
 
 SCIHOME  =  C:\Users\NOGUCH~1\AppData\Roaming\Scilab\scilab-5.5.2 


How I can change my SCIHOME Directry to my prefered Directory?
I failed to find such menu in Scilab console. (Scilab 5.5.2)

Hi Noguchi-san 

Response from Wolfgang Schulz is good. I just wish to elaborate, there 
are different settings for directories, like "home" and "SCIHOME" ... 
Please see for example: https://help.scilab.org/docs/6.0.0/en_US/home.html 

Best regards, 
Claus

In my Scilab console, I don't have such "Startup directory" in "General" item.

In general Item, I have following three items:
1. Confirmation Dialogue
2. Desktop Layout
3. Shortcut

How I can find "Startup directory" in my Scilab 5.5.2 windows version with language = Japanease case?

Hello Antoine, Nikolay,

The selection of a much performant BLAS / LAPACK implementation is very system-dependent and I don't
want to maintain something not standard / widely deployed on Linux distributions. As a reference,
the current Fedora status is to link against the library used at build-time [1]. Nicolay pointed on
a similar link for Debian which use /etc/alternatives to let the user select a library.

Currently, it is still possible to enforce a specific BLAS/LAPACK library using LD_PRELOAD
(LD_PRELOAD=/usr/lib64/libopenblaso.so.0 bin/scilab for example). However it could not be enforced
within Scilab stock version even it is known [2] that Atlas or OpenBLAS will slightly improve Scilab
speed as it is highly system / user dependent choice.

Sure thing Tim,

Thank you for pointing out those details. I will share as much as I can.

I am simulating the behavior of a battery as it is discharging into a
circuit. I recorded data from the battery (for example, the voltage and
current and internal resistance) during testing. I currently have the data
at different time steps inside of an excel file.

I would like to test this battery under different circuit configurations.
However, changing the circuit can be time consuming and expensive. I was
thinking that I could use xcos ability to do circuit simulation to
construct a basic model of the battery that I am using that utilizes the
data that I gathered. This way I can simulation the battery under different
circuit configurations very easily.

So I was wondering if there was a way that I could import my data into xcos
to construct a model for simulation.

I actually created the system to simulate the battery.

I strongly suspect that anything that would be useful would be specific
to batteries, and would perhaps be best done in batch mode to generate a
model that is then hand-tweaked and selected for use in xcos -- but I
say that in part because over the years I've come to dislike graphical
solvers. 

I think it's possible to build a subsystem out of blocks that can be
"masked" so that you can enter parameters in the usual way -- if you
could boil your battery model down so that it had a few parameters, you
could translate your measured data into parameters once, then use
parameterized blocks for the battery behavior.

Subject: [Scilab-users] reset local atoms gui
Message-ID: <1492067665016-4036210.post@n3.nabble.com>

Hello 

I installed a recent scilab 6.0 nightly builds (WIN7_64bits) which fixed an
annoying bug for me and while reinstalling some atoms module within the
atoms gui it crashes the gui and whole scilab when I pressed "previous"
button. The module was properly installed and I can use it. I can install
new atoms via the  command line console when I know the name of the package
but I can't start anymore the atoms GUI, it crashes scilab each time : how
could I repair/re-initialize the atoms GUI only (or full atoms)? de/re
-install all ?

Thanks for your help

David

Did you try more simply to copy the "former" SCI/.atoms and SCI/contrib 
directories to your new installation, and start your new Scilab? And the 
same for SCIHOME/.atoms and SCIHOME/contrib (SCIHOME changing with 
Scilab's version).
This is most often enough to get back ATOMS modules as installed in your 
last version.

Hmm... batteries: Charge storage devices which have a largely constant 
voltage in the working range but which show big changes in apparent 
voltage when they reach full charge and when the charge drops very low. 
You don't get all the electrons back. I suspect a really good model 
would relate these effects to the electrochemical processes at work. 
Also because they are "batteries" and not individual cells,  the 
aggregate behaviour will depend on the whole (in series) set.
With a sort of diodes and resistors model for the charge and discharge 
routes (somewhat different characteristics), it is possible to make a 
fair model for a battery's functional operations but I'd be a bit 
concerned if it was to try to make predictions of behaviour under 
stress  (e.g.very high discharge rates) or temperature changes (which in 
lead acid batteries reduce apparent capacity and ability to deliver 
current). There's an industry emerging for batteries with all the 
associated support equipment for creating backups for solar power etc.
So it becomes a question of how deep you want to go into the physics.

I confirm this behavior on the 6.0 branch:
After restarting, the module is well autoloaded and usable, but each time
that the ATOMS manager is called (toolbar icon or atomsGui()), Scilab 
immediately crashes.

Message-ID: <584968b3b8213b58dd0ce75fa598b207@free.fr>

Hi All

I'm wondering what is the way to solve the following study (but at the
same time I'm not sure that the problem has been correctly posed) ...
I'm a bit "disrupted" by theta scalar that depends itself on x value. 

The problem seems to be non linear and I tried (but I failed) in using
fsolve. 

Any suggestion where I've to see to? 

Thanks for your time and help 

Paul

Paul:

It appears that you're solving for y given theta and x, but y is a linear function of theta and x.

I don't have a good knowledge of what you are trying to solve, but when I solve nonlinear problems I normally either have a form of first-order derivative (scalar or a Jacobian), or some form of branching/discontinuity from which I need to choose the "best" solution. For linear interpolation, I find that it's easier to simply write a function myself than try to figure out how to make a given built-in function works.

I'm going fishing here: in your function, theta is 8x1 but your arguments for interpl are theta(:,1),theta(:,2), which presumes that theta is 8x2, so that could be a place to start looking at why fsolve is giving your grief.

Regards,


Roger.

Subject: [Scilab-users] Issue on Delete bonding key (Stack v2.1.0)
Message-ID: <1492596379162-4036227.post@n3.nabble.com>

I use function gecko_cmd_sm_delete_bonding(...);

for specific remove bonding key on Bluetooth device


this function use in 2 scenario.

1. Write remove bonding command to characteristic

                case QR_REMOVE_BONDING:
			if(data[1]==0){
				gecko_cmd_sm_delete_bonding(data[2]);
			}

2. When bonding error with 0x0305 reason code

        case gecko_evt_sm_bonding_failed_id:
       	       switch(evt->data.evt_sm_bonding_failed.reason){
       	             case 0x0305:  //repairing with the same button (not
remove key on Mobile)
       		         bondId = conGetBondingId();
       		         if(bondId!=0xFF){
       			      gecko_cmd_sm_delete_bonding(bondId);
       		         }


In 1. scenario,it great work correctly.

In 2., when i remove bonding key with id 1,the bonding id 0 will be removed.
remove 1, 1 and 0 will be removed
remove 2, 2 and 0 will be removed
remove 0, only 0 will be removed

Please suggestion for me.

Subject: [Scilab-users] Scilab checkerboard plot (grayplot)
Message-ID: <ff70db96-cd4f-ee9a-24ff-857a57a7fe5d@gmail.com>

Dear all,

I am producing a checkerboard plot with Scilab and the plot seems 
erroneously colored. The matrix I plot is attached as well as the 
scripts to plot and the plot produced by Scilab.

The problem is that the data at matrix(1,3) and matrix(1,4) are equal, 
however, on the plot produced by Scilab it is represented by different 
colors (plants vs det. feeders and plants vs carnivores on the plot). 
Let me remind you that the plot is transposed form of the matrix.

I would appreciate any help on the matter.

Kind regards,

Ekin

Hello,

The default behavior for grayplot is to paint a given pixel (a given square) with the color corresponding to its four corners.
See: "help data_mapping"
 You can either change the data_mapping after calling grayplot or use Matplot.
However, you'll have to rescale your data so that it ranges from 1 to nc where nc is the number of colors in your color_map.
See my modified function below.
Does it solve your problem?

Cheers,

Antoine

function myMTIplot(data)

[nrows ncols] = size(data);

data = [zeros(1,ncols); data; zeros(1,ncols)];
data = [zeros(1,nrows+2)' data zeros(1,nrows+2)'];

[nrows ncols] = size(data);

figure1 = scf();
a = newaxes();

colorbar(-1, 1);
grayplot(1:nrows, 1:ncols, data);

figure1.color_map = jetcolormap(32);

a.y_label.text = "Impacted Group";
a.y_label.font_size = 4;
a.x_label.text = "Impacting Group";
a.x_label.font_size = 4;
a.title.text = "Relative MTI";
a.title.font_size = 5;

Dear Antoine,

Thank you very much for the resolution. It solves my problem by 
producing a graphically consistent plot. However, data-wise, the 
colorbar does not match the plot unless I rescale it to (1,32). I want 
to be able to infer the approximate value of the data from the colors. 
However, thank you.

Kind regards,

Ekin

Subject: [Scilab-users] Monotone preserving splin
Message-ID: <1492838594106-4036235.post@n3.nabble.com>

As for the function "splin", when we set spline_type ="monotone", "splin"
returns the slope values preserving data monotonicity.
These slope values are the adjusted ones of the original slope values to
satisfy some constraints.
In order to get the original slope values, we need additional information on
the derivatives of end points such as "not_a_knot", "clamped" and "natural"
or others.
I would like to know what conditions are used when spline_type ="monotone".

Best regards

Well, I don't use colorbar.
I usually replot a dummy rectangle that contains like this:
nc=32://number of colors
Rect=[linspace(min(data),max(data),nc);linspace(min(data),max(data),nc)]
I plot it in a second axis next to the one with the actual data and than set the ticks labels by hand to display the nc values.

As Antoine wrote in his first answer, Matplot() must be used instead of 
grayplot().
The following simplified script can be used, yielding the following plot.

function  myMTIplot(data)

// Rescaling data to a given range of indices
nc  =  32;  // number of colors
zmin  =  -1;
zmax  =  1;
data2  =  (data  -  zmin)/(zmax-zmin)*(nc-1)  +  zmax;  

// Plotting
clf
f  =  gcf();
f.color_map  =  jetcolormap(nc);
Matplot(data2)
a  =  gca();
colorbar(zmin,  zmax);

a.sub_ticks(1)  =  0;
xlabel("Impacting Group",  "fontsize",4)
ylabel("Impacted Group",  "fontsize",  4)
title("Relative MTI",  "fontsize",  5);

[nrows,  ncols]  =  size(data);
a.font_size  =  3;
a.font_style  =  8;
a.x_ticks  =  tlist(["ticks",  "locations",  "labels"],  1:ncols,  ..
             ["Plants",  "Bacteria",  "Det. Feeders",  "Carnivores",  "Detritus"]);
a.y_ticks  =  tlist(["ticks",  "locations",  "labels"],  1:nrows,  ..
             ["Plants",  "Bacteria",  "Det. Feeders",  "Carnivores",  "Detritus"]);
//
endfunction

M  =  csvRead("matrix.csv");
myMTIplot(M)



It correctly maps the given data matrix:

--> data
  data  =

    0.   0.4665757   0.2895315   0.2895315   0.4778269
    0.  -0.2942464  -0.1630711  -0.1630711  -0.3005833
    0.  -0.1058069  -0.4451125   0.5548875  -0.0842439
    0.   0.0774553  -0.3547458  -0.3547458   0.0636698
    0.   0.6032754   0.3743599   0.3743599  -0.3821769

There was a mistake in the mapping (+zmax instead of +1).
And may be about data transposition. The following shows
0 in the bottom row, as the plot you posted:

function  myMTIplot(data)

// Rescaling data to a given range of indices
nc  =  32;  // number of colors
zmin  =  -1;
zmax  =  1;
data2  =  (data  -  zmin)/(zmax-zmin)*(nc-1)  +  1;  
data2  =  flipdim(data2',1);
// Plotting
clf
f  =  gcf();
f.color_map  =  jetcolormap(nc);
Matplot(data2)
a  =  gca();
colorbar(zmin,  zmax);

xlabel("Impacting Group",  "fontsize",4)
ylabel("Impacted Group",  "fontsize",  4)
title("Relative MTI",  "fontsize",  5);

[nrows,  ncols]  =  size(data);
a.sub_ticks(1)  =  0;
a.font_size  =  3;
a.font_style  =  8;
ticksText  =  tlist(["ticks",  "locations",  "labels"],  1:ncols,  ..
             ["Plants",  "Bacteria",  "Det. Feeders",  "Carnivores",  "Detritus"]);
a.x_ticks  =  ticksText;
a.y_ticks  =  ticksText;

Dear Bruno

Wiki "Monotone_cubic_interpolation" explains the Fritsch-Carlson method
which uses the finite difference approximations as the derivatives.
However, splin seems to use the derivative of interpolant as the original
slope values.
The interpolant can be determined once we set the additional constraints for
the derivatives at  x1 and xn.
I think splin with "monotone" uses some conditions for them and I want to
understand them exactly.

Best regards.

Subject: [Scilab-users] Problem with toolbox instalation - atomsExtract
Message-ID: <1492861616224-4036242.post@n3.nabble.com>

Hi,

I have installed Scilab 6 recently and I got this error while trying to
install IPCV toolbox:

atomsExtract: The extraction of the archive
'C:\Users\user\AppData\Roaming\Scilab\scilab-6.0.0\atoms\x64\IPCV\IPCV-1.1-win64-bin.zip'
has failed.

I have tried to find solution given to similar problems described in past
but none of them has worked for me. Is there any way to fix this problem?

Regards

        Dear Fujimoto,

      As far as I remember I simply introduce (long time ago) the 
pchip.f code
   (corresponding to the "monotone" option as one additionnal feature 
for the
   splin function). In this case (and also in cases "fast" and 
"fast-periodic") you
   don't get a cubic spline but a sub-spline which is only one continuously
   differentiable (s" is discontinuous at the breakpoints).

     All splines or sub-splines computed by splin uses on each interval 
[x(i), x(i+1)]
   the Lagrange-Hermite basis/representation for the underlying cubic 
polynomial, that is
   something of the fom :

        p_i(x) = y(i) H_i(x) + y(i+1) H_{i+1}(x) + d(i) K_i(x) + d(i+1) 
K_{i+1}(x)

    and so in each option the splin function computes the slopes d(i).

    The Fritsch-Carlson method uses (like the fast options) a local 
finite difference
   scheme to compute the d(i) but with modifications if the resulting 
cubic polynomial is not
   monotone. So it is not based on spline ideas like minimising the L2 
norm of the
   second derivative with additionnal constraints to ensure monotony.

    hth
  Bruno

Dear Buruno,

I see the situation.
Suppose the number of the sub-interbal is n-1 ( that is
[x1.x2],[x2,x3],...,[xn-1,xn]).
The number of unknown variables of sub-cubic polynomials is 4n-4.
When "spline_type" is "not_a_knot","clamped"or "periodic" ,we have 4n-4
constraints as follows.
2n-2 for data matching and continuity.
n-2 for the first derivatives and comtinuity at x2,...,xn-1.
n-2 for the second derivatives and continuity at x2,...,xn-1.
2 for the derivative values at near the end points which the above
"spline_type" gives.

When "spline_type" is "monotone", the constaraits are as follows.
2n-2 for data mathing and continuity.
2n-2 for the first deribatives mathing and continuity at xi and xi+1 on
sub-interval(i=1,...,n-1).
These derivatives are calculated by the finite difference method.

Best regards.

This is horrible, but should do what you intend:

B(i,1) = A(j + size(A, 1) * (k - 1));

It works because you can address a 2D matrix as a 1D matrix, with A(1)
== A(1, 1), A(2) = A(2, 1), A(size(A, 1) + 1) = A(1, 2), etc.

You may do simply:
B = A(:, [1 4]).';
B = B(:);
B = [B zeros(B)]

Message-ID: <3ec86127-e034-d7fa-a154-13cafa958f3d@tritytech.com>

Hi,

It is great to have the new computer vision released on atoms, 
especially a module which is created by Scilab Enterprises.

After so long there are many image processing and computer vision 
modules in atoms, which have their pros and cons, and this new module 
finally allows the call of almost all functions (if not all :) ) to the 
OpenCV 2.4.13 through its gateway function although not all are 
documented. I believe it will be coming very soon.

To make it better I think we could share some of our finding of the 
"hidden" functions" while waiting for the module update, the following 
code perform the image inpaint algo:

scicv_Init();

S  =  imread(getSampleImage("blobs.jpg"));

// Creating mask to remove the object at 2nd row, 2nd col. This would be 
easier after the support of the insertion for Mat implemented as stated 
in help file
m1  =  uint8(zeros(Mat_rows_get(S),Mat_cols_get(S)));
m1(110:200,150:250)  =  255;
imwrite('mymask.jpg',m1);

mask  =  imread('mymask.jpg',CV_LOAD_IMAGE_GRAYSCALE);

S2  =  inpaint(S,mask,3,INPAINT_NS);
matplot(S2)

Hello,

Thanks very much for your support.

I was also very impressed about the new IPCV module, the number and 
quality of available functions ! Particularly those related to GUI 
manipulation, that we really missed, in comparison with Matlab.
We really appreciate your work.

For years we have been wanting to provide and support an image 
processing toolbox, because this kind of toolboxes is among the most 
used, at least downloaded, by the Scilab community.

Yes indeed there are some image processing toolboxes now, especially 
based on OpenCV, but no so much, if you compare with the huge number 
available for Python.
For me several (good) toolboxes is definitely better than one at this 
moment. And they can have all different purposes, and follow different 
choices in design.

About hidden functions in sciCV, they will be more and more documented, 
version after version.

Regards,

Simon Marchetto

Hi developers,

am I to wrong to ask if the aim for IPCV and sciCV is the same?

Both toolboxes are quite welcome, but some confusion might occur if both
toolboxes are installed.

In fact, some functions are already named the same...e.g.: imread, imwrite

imread in sciCV can have flags, in IPCV it can not.

...just to mention.

I am about to ask, if it wouldn't make sence to combine the efforts, and
create only one powerful toolbox enabling openCV functionality to Scilab.
but...maybe there are good reasons for not doing so...


Best Regards,
Philipp

Using this is for submatrix but what you want is not a submatrix. In 
your special case A=eyes(5,3)

IMHO only the for loop works, in general...

Hello,
This should do the job if values different for a matrix containing only 0's and 1's:

inx=[1 2 3];
iny=[1 2 3];
A=sparse([inx;iny]',ones(inx'),[5,3]);
full(A)

If non-indexed values are not known (and A already exists) then
A(inx+size(A,'r')*(iny-1))=1;

Objet?: [Scilab-users] Problem with Matrix operation

Hello,
I want to set certain elements of a matrix to 1. Interestingly the following code fills 9 elements with 1. I expected to have only 3 elements (with index 1,1; 2,2 and 3,3) filled with 1.

A=zeros(5,3)
inx=[1 2 3];
iny=[1 2 3];
A(inx,iny)=1

Is there any way to fill a matrix with 1 where I have the indexes in 2 vectors?

Thanks for your help
Wolfgang

A  =  zeros(5,3)
inx= [1  2  3];
iny= [1  2  3];
A(sub2ind(size(A),inx,iny))= 1 --> A(sub2ind(size(A),inx,iny)) = 1A = 1.

Hi Simon,

Thanks for your comments. Just to add, IPCV is modified from SIVP, with 
extra features. 1-2 functions were taken from IPD and SIP quite some 
time ago.

 From my opinion, the common issues of all the module above are :
1. Distributing the binary cross platform, which always give the issue 
of lib version.
2. Functions from the OPENCV are "link" to Scilab with individual 
gateway, which lead to the limited functions depending on the developer.
3. Data passing and sharing between Scilab and OpenCV

 From the look of it, the scicv seems to have solved the first 2 issues, 
and near to 1k functions in OPENCV seems to have included in the dll, 
which I believe it break the bottle neck of which others (including me) 
facing. I wonder was it hand-coded? As for number 3, I believe everyone 
might have different opinion.

Yes you're right, for the moment there should be more modules, as OpenCV 
functions are being used in different functions to perform a high level 
task in Scilab, which I believe all developers would have their own way 
to do so. Eventually I believe once the framework/basic have setup, we 
could move towards it.

Just my 2 cents, sorry if any of my statements sound wrong.

Thanks.

Regards,
Chin Luh

Hi Philipp,

I believe all the developers (not just image and vision) are working on 
their topics for weeks, months or even years before the release of a 
module to public. It is good that we have atoms portal so that we could 
know who else working on the same fields and exchange ideas from there.

As for the aim for the modules, I believe all the modules should have 
the same ultimate aim: to make a good image processing and computer 
vision tools for Scilab, and possibly, replace Matlab. :)

 From my opinion, the crash of the function name are quite common, for 
example, imshow in sip using scilab graphic, using tcl/tk in sivp, using 
both in IPCV, and using OpenCV highgui in sciCV. It depends on how the 
developers want it to be. For the moment, I disable the atomsAutoload 
for both modules and load it manually whenever I need to avoid this 
problem.

As for the combine effort, what I could say is everything is possible 
with OpenSource. Someday, somehow, Scilab image processing and computer 
vision shall be taking over Matlab for this. :)

Regards,
Chin Luh

They might have used SWIG ( http://www.swig.org/ ) or some similar tool to automate the generation of the binding code.

Hello all,

I'm experiencing some weirdies with the following script (6.0.0, Windows 7) :

// **********

A=input("A = ");

B=input("B = ");

// **********

When I run the script, I can enter the value for A then I get the --> prompt.
It seems the script stopped, but if I press the "return" keyboard key, The script seem to resume and ask for B, but I then have to press twice the return key to validate it.

Does anyone else get the same behaviour ?

Shall I declare a bug?

Hi,

I am not familiar with SWIG, so I though the binding will still need 
some hand coding as well. thanks for the link.

Hello,

Yes indeed we use SWIG.

As you said, it needs hand coding.

First there is a couple of issues in the OpenCV code for SWIG, it needs 
some code patching.
Then it needs some "cleaning" to get the desired code wrapped.

Maybe because of these two issues, OpenCV abandoned SWIG for their 
Python bindings, and used a custom wrapping method.
We couldn't afford to do that.

After this, you need to implement to typemaps (SWIG code to convert the 
OpenCV data types from/to Scilab).

All of the work is not finished yet.

Simon

Dear Samuel,

Thank you for your help. This way it works as I wanted it to be. Matplot 
is the better way to go for my purposes. Thank you again.

It is a pity that the data need to be re-scaled before plotting, though. 
Otherwise, it gives a black plot with Matplot.

Best regards,

Ekin

Subject: [Scilab-users] stripchart?
Message-ID: <OFD6A17420.040BA9D9-ON8525810E.0049BE30-8525810E.004A3A96@energetiq.com>


In doing some real-time work I would find a stripchart very useful.
I have a process generating (say) 10 values/second,
that emits two values  (Time,Temperature).  This might be an xcos
calculation, or a realtime data stream.

I would like to plot this data on a "stripchart" - to show only the (say)
latest 10 seconds of data,
with the plot scrolling to the left - new points  added to the right, data
falls off the end on the left.

Digging through the docs I find no trace of such a creature.

Am I missing something obvious, or do we not have this capability in
scilab?

Thanks,
Steve

you could do this by extracting the last lines of the matrix of data
and then updating the data property of the polyline with this submatrix, see
https://help.scilab.org/docs/6.0.0/en_US/polyline_properties.html
but this needs to be tested as there will probably be side effects.

Hi Steve,

I don't think stripcharts exist in Scilab.
That being said, you can emulate them pretty easily.
See below the most simple example of such an emulation.
In a more realistic scenario, you could replace my loop by a callback function that updates the plot everytime a new datapoint is measured.

Hope it helps,

Antoine

ylabel('Data')

//dummy loop to simulate data generation and plotting

I just posted a proposition that use exactly this idea.
No side effect, but you have to handle the rescaling of the plot.

Antoin,e, thanks.
This is essentially what I was looking for.

I haven't used Xcos much - but I presume this could be wrapped up to use
there?

Thanks again -
Steve

No. It is already reported 3 times (at least), and already fixed (once, it is enough :) in the 6.0 NB branch.

You can replace all the following

>    xmax=max(newxy(:,1));
>    ymin=min(newxy(:,2));
>    ymax=max(newxy(:,2));

with only

     replot // or: replot tight

and that's it

I checked in bugzilla but didn't find.
I probably didn't use the right keywords
("input" didn't give accurate answers)

OK, I'll check this.

Thanks

Hello,

With an up to date ArchLinux box, the scilab-6.0.0 binary is failing to
run with the following error message:

I tested with the nightly builds and I've got the same error message. Do
I need some more dependency?

If it can help, the scilab compile from source on the same machine is
working fine.

Thanks by advance,
Florian
