I have used subplot to place a series of 4 graphs in one window. In each case, the xtitle on the last 2 figures are invisible.
How can I correct this.

This long standing bug should be fixed in Scilab 5.5.0. Which Scilab 
release are you using?

Thanks.
I am using version 5.4.1 on Ubuntu. If it has been solved in version 5.5.0, I will download and try it.
God bless you.

Can you try updating your OS first and Java as well. Also, I suppose that
your OS Win 7 is legit.

Brens,

Thank you very well for the answer.

OS Win7 is legit.
OS is up to date.
Java is up to date.
Java JDK is also installed.

Kind regards,
Alain.

Hi,

vet = 1:4;
disp (vet(3));

will do almost the same thing.  But note that Scilab indices start at 1, not
zero, so vet does not include the element vet[0] = 0;

HTH,
Mike.

Subject: [Scilab-users] New uicontrol layout: what bout axes?
Message-ID: <5363C22E.1090906@laas.fr>

I am a bit disappointed by the newly introduced "layout" properties.
I was expecting these properties to be available for axes in addition to 
figures and uicontrols.
This could have saved me a lot of time when generating multiple plots 
for scientific articles.
A the moment, it's a true pain in the blip to arrange by hand the 
different axes.
(Please don't mention subplot, it's quite handy but it's not really 
usable for advanced layouts).
Why were axes left behind?
Any plan to extend these properties to axes?

Cheers,

Antoine

Can you download dependency walker and use that to find out the dependency
issues. This is free utility that scans any 32-bit or 64-bit windows module
(exe,dll,ocx,etc.)

Let me know what you see.

Hi,
i am right now on the irc channel or scilab and there are almost no one
active. there are 5 users and no one is answering to my questin.

1 of all i would like to make some project for scilab under the SOCIS
program. i am interested in the Network module  project idea from the
Extend Scilab section.
i have not seen in the last column of it to have a priority flag, so i
would like to know if it has not priority flag then this project is less
probable to be selected at the end in comparition to a project that has the
priority flag?

furthermore, who is or are the mentors of the that project idea?
can i have their contacts?

i thank you in advance for the answer
best regards

Subject: [Scilab-users] strange behaviour of handle property figure_size
Message-ID: <CAGgDjFRAYnVJFbZAOuiR6tWi_v-uOW76SCHw0tWvmR1y9sCr1A@mail.gmail.com>

Hello.

I have encountered a strange behaviour of Scilab 5.5.0, which did not
happen with Scilab 5.4.1.

This happened with the following sequence:

--> wind=scf()

--> wind.figure_position=[0,0]

--> screen_size=get(0,'screensize_px')

--> wind.figure_size=screen_size(3:4)

--> plot2d(1:10,1:10)

With Scilab 5.4.1, it works fine, but with Scilab 5.5.0, the size of the
graph itself is not widened and the plot is not drawn. But, if you either
print the screen or export the graph for instance as a pdf file, then the
graph is windened and the plot is drawn (it works also if you use the
square icon in the upper right angle of Scialb graphic window, but since
all the stuff is percisely to be able to make it inside a programm, it is
not very helpful...) . If you save the graph as a.scg Scilab graph and
reload it (see file resize_5.5.0.scg), then the graph has now the desired
size, but does not provide the results of the plot2d command! (I join the
Scilab 5.4.1 result for a comparison: file reisze_5.4.1.scg).

I suspect it is a bug: right?

Is there another way to do widen automatically (that is with Scilab
commands) a graphic window that could work with Scilab 5.5.0?

Thanks!

?ric.

With 5.5.0 on Win7_x64, the result is:
  - the width of the window is exactly the screen's one.
  - the window has no status bar. Resizing it (by 0) makes the bar 
appearing.
  - the height of the window is too tall exactly by the height of its 
bottom border, in such a way that the bottom of the blank background is 
exactly at the bottom of the screen, and the border is below so not visible.
  - the plot is displayed, but with almost no bottom margin : X labels 
are displayed at the very bottom of the screen

(before  this, the OS task bar has been moved on the vertical right, in 
order to see the bottom of the screen).

Hello,

 

Is the following change of mput/mget data types "ib" and "lb" have been
reported for Scilab 5.5.0 (Win 64 bits)?

 

 

fid = mopen("mput_lb.dat", 'wb', 0);
mput(16,'lb',fid);
mclose(fid)
// outputs now long long integer with 8 bytes
 
fid = mopen("mput_ib.dat", 'wb', 0);
mput(16,'ib',fid); 
mclose(fid)
// outputs now long integer with 4 bytes

 

 

In Scilab 5.4.1 (Win 64 bits), "lb" words had 4-bytes only, if I am not
mistaken.

 

Thanks and regards

Rafael G.

According to the Scilab 5.5.0 release notes, this seems to be a bug fix:

#8862 - mget and mput could not read and write 64 bit data from binary
files.

 

(the C data type "long long integer" has 8 bytes as per Scilab 5.5.0)

Hi Antoine,

What you can do is creating axes inside "frame" uicontrols (using 
newaxes) and use a layout for the frames.

Hi; 

I try to simulate a PRBS signal generator using D flip-flops but I get an algebraic loop error: 

 c_pass2: ini_ordo (2) failed 
 xcos_simulate: Error during block parameters update.   

So, in these cases how can I solve such algebraic loops? 
Please see attached file for more details.

Thanks!

I had a look at it and I though frame only accepts uicontrols, as stated 
in the help page for uincontrols: "Frame: a container for other uicontrols."
I don't understand how I am supposed to tell newaxes to use the newly 
created frame as parent and not the current window.
If I call:


f = figure( ...
"layout"          , "border",...
"layout_options", createLayoutOptions("border", [10,20]),...
"visible"         , "on");

  c = createConstraints("border", "top", [200,100]);

  ui1 = uicontrol(f,...
  "style", "frame",...
  "backgroundcolor", [0 0 1], ...
  "constraints", c);
  a1=newaxes();

a1 is attached to f, not ui1 and placed relative to the figure, not the 
frame...

I'm confused...

I reported two bugs for these inaccuracies in the help pages:
13383: newaxes optional argument (handle to the parent) is not present 
in the help page
13384: uicontrols description of frames does not mention axes entities 
(only uicontrols).

Cheers,

Antoine

Hello,

The algebraic loop error is linked to the fact that clock-like data link
are not handled the same way as event link. To remove this error you
should add a delay (1/z) block after the LOGICAL_OP("OR") block to
delayed the signal by one execution step.

Thanks Samuel.

IDNHVM ;-), since I still do not:
- why the behaviour differs from Scilab 5.4.1 to Scilab 5.5.0; is it a bug
or an intended change of behaviour? And why?
- if this betrays a bug;
- how to reocver Scilab 5.4.1 behaviour with Scilab 5.5.0.

Eric.

Message-ID: <5c60-53680700-3-1c342c20@91352763>

Hi everyone,

I just started to play again with GUI in scilab to experiment with the new layout system and I re-discovered my old frustration with sliders: there are no graduations on them making them difficult to use in practice.
Example: slider value goes from 830 to 895: where should I move the cursor to get around a value of 850 or 870, 1/3, 2/5, 3/5?
As anyone found a workaround to this problem?
I tried to display an axes above to the slider to use the axe's ticks as graduations for the slider.
But there is some padding left and right from the slider that makes it difficult to align the start and end of the slider "scale" respectively to the first and last ticks of the axes.
Am I this only one annoyed by this "limitation"?
What about a "wishlist' bug report to add this property to the sliders?

Cheers,

Antoine

Thank you. 
But when I add a delay block and convert its output to int8, I get the
following error: "Problem in port size or type" 
I think this issue is similar to the bug # 10781 (please see:
http://bugzilla.scilab.org/show_bug.cgi?id=10781). 

If possible, please add a delay and a convert block to the model, and then
let me know if you get the same error. 

Thank you again.

Subject: [Scilab-users] Plotting problem - subplot with 2 y-axis
Message-ID: <07A8AF089844A549B0F0CCC727AF31AA56FD3FEC@OVEKBG.ove.at>

Hello,
I have a Scilab script with a subplot containing 2 y-axis perfectly working in Scilab 5.4.1 but I have problems in Scilab 5.5 (everything on Win7 64bit).

I attached the same plot received with both Scilab versions.

Basically I do the following:
    subplot(2,1,1);
    plot(amp,DE(sensor_nb,:),"-s","MarkerSize",4,"MarkerFaceColor","b");
    set(gca(),"data_bounds",matrix([0,xmax,0,100],2,-1));
    a=gca();    
    a.title.text=main_title;
.
.
    a1=newaxes();    
    a1.filled="off"; // the background of the graphical area should be
    a1.axes_bounds=a.axes_bounds;

    plot(amp,anz(sensor_nb,:),'r');
    set(gca(),"data_bounds",matrix([0,xmax,0,100],2,-1));
    a1=gca();    //get the handle of the newly created axes
    a1.tight_limits = "on";
    a1.y_location = "right";
    a1.axes_visible = ["off","on","off"];
.
.
    subplot(2,1,2);
.
.

Any idea what is going wrong? Maybe the axes_bounds are not correct?
Thanks for your help
Wolfgang

Dear all,

I've got weighted data and i'd like to plot an histogram

For instance, income distribution from people within revenue segments.
Any idea?

	boundaries ?
Message-ID: <1399533264262-4030445.post@n3.nabble.com>

Hi!

I'm trying to solve simultaneous equations using Scilab.
The constraints of the variables are like 0 < x1 < x2 < 1.
A program using leastsq shown below does not work:
----------------------------------------------
binf =  [         0,  xopt(1)];
bsup = [xopt(2),          1]
[fopt, xopt] = leastsq(myfunc, 'b',binf,bsup, x0)
----------------------------------------------
Obviously because xopt(1) and xopt(2) are not determined 
before calling leastsq but they are used as boundaries.

So, could somebody tell me how to solve this kind of problem ?

toshi

Message-ID: <536bd20b.48a7ec0a.5349.ffffb26c@mx.google.com>

Dear colleagues,


I have two functions f1(x) and f2(x). Using the following formula:? 

 



to calculate the results, get: 5.125[units]. 

I tried to calculate separately by F1=fft(f1) , F2=fft(f2) and then multiply stems one by one and adding the results. I found two problems:

1 - I have been used Hamming window to minimize noise. The amplitude of each signal changes and the final results too;

2 - When I change the number of samples, the results change too.

None the results in 1 or 2 are igual or close to 5.125 (this is right).

What am I doing wrong?

Can someone help me? 

Thanks a lot.

This is a question about numerical computing rather than Scilab itself.
Anyway, why do you use some FFT instead of some straightforward 
integration function (such as intg()) ?
FFT would be useful whether the expected result would be e.g. the 
cross-correlation function of your f1() and f2() ;
but it is not the case : no lag appears in the integrand between 
arguments of f1 and f2...

Hello,

Can you try to reproduce using the official Scilab version ? If it
works, just file a bug on the ubuntu side ; if not, use our bugzilla.

Did you try to generate the code using an Scilab/Xcos demo (exemple
Kalman.zcos) ?

You are a talented scilaber so I guess you already digged in the usual sources.

Maybe you can cheat on your favorite software and use R.
There seem to be several packages to do this, such as

weights
http://cran.r-project.org/web/packages/weights/weights.pdf

plotrix
http://svitsrv25.epfl.ch/R-doc/library/plotrix/html/weighted.hist.html

ggplot2

I guess one way is to use qpsolve (or qp_solve or quapro), using 0<xi<1 
as bounds, and adding the linear constraint x1-x2<0 (or maybe x1+x2 <= 1 )

Ha ha
ggplot2 is my workaround right now.
Actually i then decided to switch to python, so i am now trying to do 
this with matplotlib.

Anyway, i'm still interested on a way to do this in Scilab, and I 
actually believe it should be implemented in histplot

I Agree.

We should add it on our Bugzilla Christmas list.

A quick search on that famous similar commercial software seem to show that it is not native either. Contributors proposed .m files on the File Exchange, or do it manually.

Message-ID: <DUB109-DS2DB9347B86CF628803EB0CC350@phx.gbl>

Hello,

Does anyone know how to properly display a large amount of plain text stored
in a string variable of size (N,1), i.e. with N text lines of variable
length, outside the Scilab console window?

For instance, is it possible to issue Scilab command to display the text
variable in one of Scinotes or Scipad tabs?

Thanks and regards,
Rafael G.

Hi

I would export it with *csvWrite *then open it with an editor. on 
windows you can even use *winopen *to open it with the defautl editor. 
on all platforms you can use *editor *to open files in editor.
*write *is also a function used to export text to the hard drive, i 
believe. but I prefer using csvWrite for everything.

Hi Rafael

Yes it is possible to save the string to a file, then load it into the 
Scinotes editor. I've done this for years.

fd  =  mopen(filename1,'wt')

mfprintf(fd, yourstring)

mfprintf(fd,"\n");
mclose(fd);
if  (isdef('editor')  |  (funptr('editor')<>0))  then
   editor(filename1)
end

So do i. There is already a ongoing thread on bugzilla about histplot(), 
histc(), & hist3d() (partially implemented for Scilab 5.5.0 by Paul and 
Mehran):
http://bugzilla.scilab.org/show_bug.cgi?id=12925
Making histplot() accepting weighted data is somewhat planned, but time 
was missing (to me) to design a full SEP about histograms management in 
Scilab (please see the thread for ideas).

For weighted data, two cases are possible:
1) input data are already fully categorized in predefined bins. 
histplot() must just plot them
2) input data are already in some bins with related populations 
(weights), but bins must be aggregated into "overbins" before plotting 
the resulting populations.

Hi Claus and Adrien,

 

Thanks for you feedback and workaround.

Not the cleanest way of doing this but it works.

Below Claus code with small syntax modification to handle my Nx1 text string
and also cleaning the temporary disk file:

 

fd = mopen("text_out.txt",'wt');

mfprintf(fd,'%s\n',my_Nx1_string);

mclose(fd);

if (isdef('editor') | (funptr('editor')<>0)) then

    editor("text_out.txt");

    mdelete("text_out.txt");

end

 

 

PS:

In my case editor() opens Scipad 8.72.

 

Regards

Rafael G.

Subject: [Scilab-users] Bicycle Dynamics
Message-ID: <1399916961487-4030466.post@n3.nabble.com>

Hello All,

First time poster here. Apologies in advance I am doing something in a wrong
way or not following the conventions. 

I have been using Scilab for few days now and I am trying to model a Bicycle
with it. The output of the system I modeled is not what i expected. 
As a first time user i am not so sure whether I have done the steps right or
modeled the system right in first place. If anyone with some modeling
experience can comment on whether what I have done is wrong or right it
would be much appreciated.

To start with I modeled the bicycle as an inverted pendulum. and I am trying
to control the bike with steering angle.
<http://mailinglists.scilab.org/file/n4030466/BikeLeanForces3.png> 

As we can see the horizontal force is a function of turning radius and it in
turn a function of steering angle.
Function between steering angle and turning radius is given by,
<http://mailinglists.scilab.org/file/n4030466/delta2r.png> 

After simple algebra I got the dynamic equation of the bike to be,
<http://mailinglists.scilab.org/file/n4030466/CodeCogsEqn.gif> 

1. Can anyone please comment up to this point what I have done is correct ?

Then I tried to model this equation in XCOS and this is the block diagram I
came up with.

<http://mailinglists.scilab.org/file/n4030466/bike-xcos.gif> 

2. Can anyone please comment up to this point what I have done is correct.
May be I have committed a stupid mistake like changing +-?

The output of the system came like this for a delta input in the steering
angle.
<http://mailinglists.scilab.org/file/n4030466/Output.gif> 

3. I guess the output should be diverging theta with exp like behavior. But
may be the output is linear because with theta change there is also the
turning radius changes and it compensate the m.g.sin\theta.l term. 

If anyone could confirm that the model seems to be realistic/ or correct I
would be so thankful. 

Thanks again
Gona.

Dear Sir or Madame,

I am starting to use Scilab instead of Matlab more and more so I have to translate?
some code from a Matlab M-file into Scilab.

So when I write an argumental function in Matlab I can write it for example like:

U_q=@(f_u) k_U*2*pi*f_u;


Now my question:

Which operator do I have to use in Scilab instead of =@ ?

Thank you,

Best regards,

Patrick Seeb?rger

Dear Adrien,

Thank your for your reply and letting me know qpsolve.
The function qpsolve really makes linear constraints
and so it may help me.

Unfortunately, my equations to be solved are not linear
but trigonometric.  The problem is not straightforward, 
but I will try to check whether it is possible or not 
to change the problem into linear problem.

Thank you very much in any way.

Hello,

Lets start with physics:

> I modeled the bicycle as an inverted pendulum. [...]
> <http://mailinglists.scilab.org/file/n4030466/bike-xcos.gif>

I guess this is the bicycle seen from behind (or front, no matter), and that the frame of reference is the bicycle.

> Function between steering angle and turning radius is given by,
> <http://mailinglists.scilab.org/file/n4030466/delta2r.png> 

You forgot to define w, delta and phi.

If phi is the adherence angle, then it is a limit is not in the relationship as long as theta <= phi.

The rotational equilibrium in the frame of reference is just
v^2/r/g = tan(theta).

>From what I understand you're trying to do, we don't have the same equation in the end.
So, maybe you should clarify the points above (what is represented, what is the frame of reference, what are the different variables),
to see if I misunderstood something, who is right.

Only then can we go on with the next point: Scilab/Xcos.

Now concerning

> The output of the system came like this for a delta input in the
> steering angle.
> <http://mailinglists.scilab.org/file/n4030466/Output.gif> 

You did not specify what you are drawing.
You may think that we can understand from the block diagram you provided.
However, you want to check the consistency with the reality/physical laws, so we must know what you expect to draw.

Regards.

I'm not a Matlaber, but a quick search on the Mathwork website tells me you're trying to deine an anonymous function, right?

I don't think such things exist in Scilab.

You can define the function with

function [y]=U_q(f_U)
    y = k_U*2*%pi*f_U
endfunction

or with

deff("y = U_q(f_U)", "y = k_U*2*%pi*f_U")

Now, if it is important for you to have an anonymous function and not a "normal" function, you should tell us why so we can give you the "right" solution.

Here is the test script:
If you enable the line 
//a.x_label.text="Sensor Amplitude [LLP-Units]";
You see the same problem.
Is it a bug?
Thanks for your help
Wolfgang


x=0:0.1:2*%pi;
y=sin(x);
   
subplot(2,1,1);
plot(x,y,"-s","MarkerSize",4,"MarkerFaceColor","b");

a=gca();    
a.title.text="Test";
//a.x_label.text="Sensor Amplitude [LLP-Units]";
a.y_label.text="Relative Sensor DE [%]";

a1=newaxes();    
a1.filled="off"; // the background of the graphical area should be
a1.axes_bounds=a.axes_bounds;

plot(x,4*cos(x),'r');
set(gca(),"data_bounds",matrix([0,6,-2,2],2,-1));
a1=gca();    //get the handle of the newly created axes
a1.tight_limits = "on";
a1.y_location = "right";
a1.axes_visible = ["off","on","off"]; .

subplot(2,1,2);

You should keep in mind that some functions that are available in toolboxes for Matlab are included in Scilab (e.g. the optimisaiton functions).

So the best is to look first at
http://help.scilab.org/
and either browse by topics,
or type the name of the Matlab function and see if it fits.

Then look at the modules, described  at
http://atoms.scilab.org/

I've just updated from 5.4.4 and found out that Scilab 5.5.0 merely flashes its GUI before crashing.

Should I reboot?? I wasn't asked to.

Hello Wolfgang,

If you were dealing about the mismatch between both axes frames:
This is a side effect of the new axes.auto_margin attribute.
In order to fix it in your example, you may just add
a1.margins = a.margins;

Hi Fausto

I don't remember restarting the PC. Scilab should work without restart, 
AFAIR. Scilab shouldn't crash on you, I think something went wrong 
during your installation.

Hello,

As answered by Christophe, you shall use deff(..).
In Scilab, all functions are somewhat anonymous, in the way that their 
names are "handles"
that some functions may accept as is (functions names are some variables 
with specific types).

Some examples:
deff("y = what_do_you_want_to_do(action, param)", "y = action(param)")
-->what_do_you_want_to_do(sqrt, 2)
  ans  =
     1.4142136

-->what_do_you_want_to_do(max, [2 -1 3 0])
  ans  =
     3.

-->what_do_you_want_to_do(min, [2 -1 3 0])
  ans  =
   - 1.

It is possible to make aliases of functions as of variables:

-->quadratwurzel = sqrt

-->quadratwurzel(2)
  ans  =
     1.4142136

and so on.

HTH,
Samuel

Hi Christophe,

first of all let me thank you so much for your time and effort on this.

I was referring to this wiki article from the beginning. 
http://en.wikipedia.org/wiki/Bicycle_and_motorcycle_dynamics

About the points that you have raised,
> I guess this is the bicycle seen from behind (or front, no matter), and
> that the frame of reference is the bicycle.
	Yes it is the bicycle seen from behind

> You forgot to define w, delta and phi.
<http://mailinglists.scilab.org/file/n4030480/CodeCogsEqn4.gif> 
	where r is the approximate radius, 
	w is the wheelbase, 
	? is the lean angle, 
	? is the steer angle, and 
	? is the caster angle of the steering axis

> The rotational equilibrium in the frame of reference is just v^2/r/g =
> tan(theta).
	That is true for the rotational equilibrium. But what I have done is
deriving an deferential equation describing the system.
<http://mailinglists.scilab.org/file/n4030480/CodeCogsEqn-Derive.gif> 

> You did not specify what you are drawing.
	In the first xcos schematic what I have shown is how I implemented above
equation in xcos.
	In the second picture what I have shown is the impulse response of the
system ( The out put theta to the impulse input delta)

Thanks a lot for the effort and I really do appreciate it.

Best
Gona

OK, that clarifies a bit.
I guess we can trust the Wikipedians (and have no time to make the calculation myself).

> That is true for the rotational equilibrium.

Yes, I thought about it just after clicking "send", we are here in dynamics.

> In the second picture what I have shown is the impulse response of the

OK.

I just wonder what you call l.

If it is the height of the center of gravity when the bike is upright, then it is not the length that is in the moment of inertia. Your bike+biker is not a uniform rod.

You may define a radius of gyration for the body about its center of gravity, then apply the Huygens-Steiner theorem where we find l.

But this is rather complicated as you don't have the radius of gyration. You might keep I as a parameter itself.
But this is just a proportional factor and should not have a qualitative influence.

Then: when you calculate the torque of the forces, it seems to me it should be
mg*l*cos(theta) - (mv^2/r)*l*sin(theta)
and not the contrary.

Or?

Or not.
Sorry, you're right, I messed the axes up.
A shame for someone writing "Mechanical calculation engineer" in his signature ;-)

So, your calculation seems globally right.

Now, your question "If anyone could confirm that the model seems to be realistic/ or correct" is not obvious:
I ride my bike everyday to go to work, and if I have a pulse in the steering angle, I correct it with my balance...

Not sure 'bout what I'm saying (and I wrote enough silly things yet), but once delta goes back to 0, r is back to infinity (straight movement),
so what you should see is the biker falling.

Hello, I recently installed Scilab (for the first time)
I was trying to check everything but everytime I open Scilab Advanced CLI, 
I receive this warning message: 

libEGL warning: DRI2: failed to authenticate

My OS is Ubuntu 14.04,

What should I do to get rid of this and what are the implications?

I have java installed if that helps

Thanks in advance

	Yes. Thats true. What I am concerned here is that whether it falls with
constant angular velocity or  with 	accelaration. so shouldnt it be an sin
diverge .only acting force is mg.l.sin\theta at this point since centrifugal
force is 0. I am wondering how come it is a linear

Note my official Scilab address is via     mjmccann at ieee.org (IEEE in US)
but my email client uses my address     mjmccann at iee.org      (IEE now 
IET, in UK)

If you are interested in bicycle dynamics, stability and control you 
should look at the special edition of the IEEE Control Systems Magazine, 
October 2006, Volume 26 number 5, "Advances in Motorcycle Design and 
Control" There are hundreds of references going back to the late 1800s.  
Key authors in this journal were Alessandro Beghi and Ruggero Frezza, 
also David J. N. Limebeer and Robin S. Sharp. I happened  to keep a copy 
for personal interest, but I haven't worked in this field. It's all 
there, stability, wobble, weaving, shimmy, stabilization methods and 
geometry effects. On page 110 there's a picture of Albert Einstein 
turning a corner on a bicycle with his quote, "Life is like riding a 
bicycle. To keep your balance you must keep moving".

Thinking about the problem discussed here in Scilab/Xcos it seems to me 
that you are interested in the rotation about the contact line with the 
road, that the radius of gyration will be dominated by the height of the 
rider's  CG above the road unless it's a motor bike in which case the 
mass of the bike could well dominate the analysis and furthermore, since 
turning involves rotation about a vertical axis and at high speed, the 
wheels can have significant angular momentum (gyroscopic effect) you may 
have to consider the angular momentum in 3 space. Good luck.

Hello,

why is that I cannot find the module in the subject within xcos' palettes?
(running scilab 5.5.0 under xubuntu). I came aware of such module by the
link shown below.

Thanks,

Subject: [Scilab-users] Problems with Arx-algorithm
Message-ID: <1400145977634-4030499.post@n3.nabble.com>

Hello,

I did some measurements and data analysis on a system. Now I want to let
scilab calculate a transfer function with armax algorithm but I'm running
into problems.
input_short is the input vector and the same with output_short. Then I do:
[arc,resid]=armax(8,5,output_short,input_short)
[z]=arsimul(arc,input_short);

And afterwards I'm plotting the real output and the simulated one:
plot(scalar,[z' output_short']);

Now here are four different value pairs of the plot:
<http://mailinglists.scilab.org/file/n4030499/SimulatedVsReal.png> 

And here is the real system with input and output: (Is longer, the above is
only a extract)
<http://mailinglists.scilab.org/file/n4030499/real_system.png> 

Now I really don't know what to do to get satisfying results? Anyone got an
advice?

Thank you so much!
Florian

Hello,

Neither 32- nor the 64-bit versions of Scilab 5.5.0 seem to like this computer and it's
64-bit W7 Ultimate OS.? The installs go fine, but when I start Scilab up all it does
is to flash its GUI for a tenth of a second and then vanishes.? Task Manager says it's
not there either running on the background yet invisible or not responding.

What could that problem be?? Can anyone help?? Have any of you had this problem
before?? What other packages not self-contained in the installer do I need?? I have
Java 8 64-bit, would that be the problem?? Does Scilab generate an error log report
I could post here/somewhere to get some insight on the problem?

Many thanks in advance.

Subject: [Scilab-users] CLSS Problem. System doesnt behave as expected.
Message-ID: <1400232592468-4030506.post@n3.nabble.com>

Hi all,

I was trying to model a linearized system in Xcos with CLSS block in state
space form. But the output of the system doesn't seems to be realistic at
all.

The equation I wanted to model is this.

<http://mailinglists.scilab.org/file/n4030506/Pendulum-Diff.gif> 

With small angle approximation, the state space representation came as,

<http://mailinglists.scilab.org/file/n4030506/Pendulum-CLSS.gif> 

The system I modeled with Xcos is as follows with following parameters.

<http://mailinglists.scilab.org/file/n4030506/CLSS_System.gif> 
<http://mailinglists.scilab.org/file/n4030506/CLSS-Parameters.png> 

The output of the CLSS system came as,

<http://mailinglists.scilab.org/file/n4030506/CLSS_Output.gif> 

I modeled the exact same system as a non linear model in Xcos and output
appears to be correct.

<http://mailinglists.scilab.org/file/n4030506/Pendulum-Continious_System-Xcos.gif> 
<http://mailinglists.scilab.org/file/n4030506/Pendulum-Continious_System.gif> 

Can anybody please let me know if I have done something wrong in this simple
system and does the CLSS work as its expected to be ?

Thanks a lot in advance

Hi,

Thanks all for the support.

Now the model is working fine. I have changed nothing. I am not sure what
caused the previous plot to be incorrect. May be the cashed variables has
caused this damage.

<http://mailinglists.scilab.org/file/n4030507/Bike_Correct.gif> 

I have experienced another problem when I tried to use CLSS block in Xcos
and I opened another thread on that topic here.

Subject: [Scilab-users] PID tuning with Optimization
Message-ID: <1400234315932-4030508.post@n3.nabble.com>

Hi All,

I was trying to tune my PID controller following this article.
http://wiki.scilab.org/Xcos/Examples/PID

I have setup my environment like this,

<http://mailinglists.scilab.org/file/n4030508/BikeModelWith_PID.gif> 
<http://mailinglists.scilab.org/file/n4030508/BikeContextParameters.gif> 

And up to the first simulation, the process went well.

<http://mailinglists.scilab.org/file/n4030508/Bike-SimulationOK.gif> 

I got a warning for the CMSCOPE but I guess it has nothing to do with this
problem.
*CMSCOPE('set'): Wrong size for block parameter 'Refresh period': 2
expected, getting 30 30 30 30 *

But when I tried to start the optimization, I got this error.

*-->[f_opt, x_opt] =
optim(my_optim_pid,'b',Lower,Upper,x0,algo='qn','ar',MaxEvalFunc,MaxEvalFunc,1e-3,1e-3,[1e-3;1e-3]);
 
 CMSCOPE('set'): Wrong size for block parameter 'Refresh period': 2 expecte 
      d, getting 30 30 30 30

at line       2 of function my_optim_pid called by :  
unc,MaxEvalFunc,1e-3,1e-3,[1e-3;1e-3])*

My f_pid function goes like this.

*function y = f_pid(x)
  global Iter;
  %scicos_context.l = l
  %scicos_context.g = g
  %scicos_context.v = v
  %scicos_context.phi = phi
  %scicos_context.w = w
  %scicos_context.P  = x(1)*Pfact;
  %scicos_context.I  = x(2)*Ifact;
  Iter = Iter + 1;
  Info = scicos_simulate(scs_m,list(),%scicos_context,flag='nw');
  y_error = mean(abs((block_output('values')(:,1) - 
block_output('values')(:,2))));
  y_diff  = mean(abs(diff(block_output('values')(:,2))));
  y = 0.5*y_error + 0.5*1*y_diff; ...
  printf('Evaluation %d - P = %f I = %f y = %f (y_error = %f, y_diff =
%f)\n',Iter,x(1),x(2),y,y_error,y_diff);
endfunction*

I guess the problem lies in the block_output variable.
When I tried to see the content of the block_output('values')(:,2) I got the
same error.

*-->block_output('values')(:,2)
                            !--error 21 
Invalid index.*

I guess in my system the block_output is not in the same dimensions as that
of the example shown in the article. How can I fix this issue.

Anyone please shed some light on this issue ? 
and how can I add the D gain in to the optimization ?

any help is highly appreciated.

Thanks
BR
Gona

Hello,
 
Does anyone know how if it is possible to propose a File name inside the GUI
of uigetfile?
 
For example:

filename= uigetfile(["*.txt"],"", "Write output file name", %f);


 
It would be handy to be able to propose a file name in uigetfile, based on a
Scilab variable related to data to be saved, instead of having to type it.
 
Thanks and regards,

Hi Serge,

Merci pour votre r?ponse.

Unfortunately, there's not such a "glxinfo" command on my W7 system.? But I checked
the info about the graphics card (an AMD HD 6670) and apparently OpenGL is there
and active (version 6.14.10.12874).? I even updated the driver -- to no avail.? Scilab
5.5.0 keeps crashing.

This is frustrating because I don't remember it ever happening before with Scilab or
any other application.

I don't have to use Scilab, but I like it and would keep it if I could.? But, much to my
regret, it seems that I either go back to a previous Scilab version or quit Scilab
altogether.

Regards,

Fausto

Hi.

>From the simulation point of view, the resulting model may not be
satisfactory due to two main reason; 1: inappropriate model structure,
2:Nosiy data.

If you intend to use only the ARMAX model, then you should change the orders
of the polynomials so that a good estimated model can be obtained. 
So, you've also change the orders four times. Why not try more other orders? 

As far as I know, the fitness value between 85-90% is acceptable. So, as a
side note, the normalized root mean square error can be used to compare
estimated data (ysim) with measured data (y): 
fitness_percentage = 100*(1-(norm(y-ysim)/norm(y-mean(y)))) 

However, if the fitness value was not admissible, the measured data may be
contaminated by noise. Then, you should filler the measurements before
starting the parameter estimation. Use the frequency response of an
estimated model to find the frequency range which needs to be filtered.

Hi. 

It seems that your model is not valid. I think you wanna simulate the
equation of the motion of a 1-dof robot arm or a simple pendulum. Therefore,
the correct model can be derived from Euler's law as below (You've not
considered the effect of gravity correctly):

 mL^2(thetadoubledot) + gLsin(theta) = Tau

However if you wanna simulate your given model, then state equations become: 
x1=theta --> xdot1=thetadot=x2
x2=thetadot --> xdot1=thetadoubledot=x1/L + Tau/mL^2

So, correct the matrix B as below: B=[0, 1/mL^2]


Instead of using Xcos, you can simulate the model in Scilab environment by
using ode function. That is the response that you should expect to see in
Xcos simulations.

clc, clear
L=1; m=1; Tau=1;  
function xdot=Model(t, x) 
    xdot(1)= x(2); 
    xdot(2)= sin(x(1))/L + Tau/(m*L^2); 
endfunction 
theta0=0; tethadot0=0; t0=0; 
t=0:.01:10; 
x0=[theta0; tethadot0]; 
y=ode("rk",x0,t0,t, Model); 
subplot(211) 
plot(t, y(1,:))  
set(gca(),"grid",[1 1]*color('gray')); xtitle('$\theta(t)$', 'Time (s)',
'Angle (rad)'); 
subplot(212) 
plot(t,y(2,:))  
set(gca(),"grid",[1 1]*color('gray')); 
xtitle('$\dot{\Theta}(t)$', 'Time (s)', ' Angular Velocity (rad/s)');



To simulate the non-linear system in Xcos, you should use the "EXPRESSION"
block to handle mathematical functions (e.g. sin(theta)). Therefore, your
non-linear scheme also appears wrong.

AFAIU, uigetfile and uiputfile are not intended to propose a (new) 
filename but to interactively select an existing one.
If a new file must be created, why do you want to locate it 
interactively (but for selecting the homing dir, with uigetdir) ?

Samuel

Hi,

I have created my own Xcos Block.
I try to share variable between them without any link.

I want to have the same behavior than the GOTO/FROM Blocks, but i want to
manage the variable inside my own block.
My blocks are developped in C, i thought use the globlal variable, but i
dont know how to use it in C files.

Thanks,

Paul

Right, /ui//*put*//file/ could also be used to set interactively in a 
once a new filename (with a default proposal) in the right chosen dir.
A wish that could be reported in bugzilla.

Hi; 
Please see the state equations above.
So, you must also correct the matrix A:  A= [0 1; 1/L 0]

Hi,

I found out whats wrong basically in my system I have modeled. I hadnt had
the input pushed in to the workspace variable block_output.

I fixed that issue and now the system and output look like this.

Note: I used D gain fixed at 1 as my system is unstable without D

<http://mailinglists.scilab.org/file/n4030515/SystemDiagram-Opt.gif> 
<http://mailinglists.scilab.org/file/n4030515/BeforeOptimization.gif> 

When I initialized the x0 variable to [1;5] (Initial P and I gains), The
optimization routine calculated the optimum gains 1 and 5 for P and I
respectively after 90 iterations.
*
Evaluation 90 - P = 0.999831 I = 4.997351 y = 0.007559 (y_error = 0.015119,
y_diff = 0.000000)
*
and the system response for the square wave looks like this
<http://mailinglists.scilab.org/file/n4030515/BeforeOpt-Prog.gif> 

Then I tried to initialize the x0 variable to [1;1] and started the
optimization routine; after 72 iterations I got 1 for P and 1 for I as
optimal gains.
*
Evaluation 71 - P = 0.999973 I = 1.001996 y = 0.240250 (y_error = 0.446943,
y_diff = 0.033557)
Evaluation 72 - P = 0.999973 I = 0.997996 y = 0.240493 (y_error = 0.447429,
y_diff = 0.033557)
*

1. Why is that the optimization routine seems to take optimal values very
close to the initially given values. ? I am not a pro but I guess it might
have something to do with quasi-Newton method which had been used in this
example as its only possible to find local minima ? In this case do we need
to guess the correct value approximately before running the optimization ?
 
2. How can I incorporate D gain in to this.

Thanks a lot in advance.

Hi Mehran,

Thanks a lot for your reply.

I tried changing the B matrix as you suggested and still the system gives
out a result which is not acceptable.

<http://mailinglists.scilab.org/file/n4030516/BCorrected.gif> 
<http://mailinglists.scilab.org/file/n4030516/CLSS-output.gif> 

Can you please let me know what I have done wrong here assuming my equation
is correct.

As I have shown above I have modeled the same equation in Xcos Schematic and
I got the output as you have suggested in your simulation.

<http://mailinglists.scilab.org/file/n4030516/Xcos-Schema.gif> 
<http://mailinglists.scilab.org/file/n4030516/outputXCos.gif> 

Thanks in advance
BR
Gona

PS: Sorry about my previous misleading info stating non-linear system. I
just referred  to the Xcos Schematic and thanks a lot for correcting my
equation. I got your point.

Hi,

Its none of the guesses I made above. In the example tuning shown in scilab
article initial values are set to [1,1] but final P value comes around 50.

I am posting here my system in SS form and TF form thinking it might give
some insight. 
<http://mailinglists.scilab.org/file/n4030525/SS-Bike.png> 

<http://mailinglists.scilab.org/file/n4030525/TF-Bike.gif> 

Does the optim function work in the order of my TF ? or do I need to think
about another optimization algorithm. ?

Any feedback is really valuable for me and I do appreciate your time and
effort on this.

Thanks in advance.
BR
Gona.

Hello,

To "share a variable" at simulation time, I suggest you to implement
your own data management, store any shared pointer in the block->work
field at flag=4 (Initialization) and reusing it while the simulation
goes on.

GOTO/FROM blocks are handled during diagram transformation and do not
have any simulation function.

Regards,

Message-ID: <CAKBMpNbdSSe6+8x_CE8-dwghi8N75mDp=r7GJ9Jo1vN5qBHtpg@mail.gmail.com>

Hi Scilab community!

I'm new to Scilab, and the AR-HMM and VAR-HMM solving capabilities of
GROCER are what interest me.

I have a question relating to Chapter 23 from the GROCER manual[0].  This
is the univariate MS-AR(3) solved using the function ms_reg_d() on the
us_revu.dat data included with GROCER.  I have made no adjustment from the
example statements in Chapter 23.

The example output is shown on pages 4 and 5 of the Chapter 23 module.
 Compare that against the output I receive.

http://fpaste.org/102978/14004958/

Here are my questions:

1.  The numerical output is completely different.  I expected it to be the
same since the data is provided by GROCER, and I've done the example
exactly as shown in Chapter 23.  Is there some explanation to why the
solved solution I receive is different than the example output in the
chapter?

2.  I see output like %i*8.4469016 which seems like an error because %i
looks like a variable that yet needs to be replaced, and then multiplied to
get to its final value.  Is this some kind of bug or error?

Thanks for any help the community can provide.  We'll be using this for a
seminar on HMM, AR-HMM, and VAR-HMM at North Carolina State University.
 I'm also a developer, so I really appreciate all the effort that has been
put into scilab and GROCER.

Thanks,
Brian

Subject: [Scilab-users] How to mantain the xcos superblock when generating
	code from it?
Message-ID: <537A7C6F.1000101@gmail.com>

Hi to all,
I do not have a great experience with scilab and none at all with xcos, 
however having more than 8 years of expertise with matlab\simulink I'm 
trying to use xcos to see if and how it can generate code from a model.
So I've created a very simple model (2 input ports, a sum block and an 
output port). Then I've created the superblock selecting the sum one and 
I've configured the inputs ports to be scalar ones. Finally I've 
selected the superblock and I've created code from it.
Now the problem for me is that apparently it has erased the original 
xcos block and has created a new block which calls the c code generate 
from it.
If I do the same thing in simulink (namely if I create an sfunction of a 
block), it creates a new block in a new model without erasing the 
simulink original one.
The problem with the way xcos generates code from a block is that in 
case the model is a very complicated one and the user creates code from 
it, he loses the possibility to modify the xcos block since at the end 
he has only the c code.
Is it the way it should behave? Is it possible to configure xcos so that 
not to erase the original block? Am I doing something wrong?

Hello,

I had the same problem in a block created with scicos_block4.h

If you want to use get_scicos_time() in a Block with a scicos_block4.h file,
you have to have include scicos.h.
I don't really know why but it's work ^^ 

Paul

Hello Brian

Sorry for this late answer, but I have been quite busy these days.

I did not notice the problem with this version of the MS programs. Indeed I
have changed the optimization device of all GROCER programs and I have not
adapted the defaults for the MS programs.

If you run:
--> global GROCERDIR;
--> load(GROCERDIR+'\data\us_revu.dat')
--> bounds('1967m4','2004m2')

--> nb_states=2
--> switch_var=2 // variances are switching
--> var_opt=3 // unrestricted var-cov matrix

-->
r=ms_var('cte',3,'100*(log(us_revu)-lagts(2,log(us_revu)))',nb_states,switch_var,var_opt,'prt=initial;final','opt_convg=0')
(see chapter 6 of the manual for explanations)

Then the results of the ms_var demo is restaured.

I will change the default in Grocer next version .

Regards.

?ric.

Subject: [Scilab-users] Why so slow?
Message-ID: <llg7qj$lr1$1@ger.gmane.org>

Hello,
I need to read in a csv of about 360.000 lines with date and numerical 
values. Attached is a sample excerpt of that file.

So far I did:
==== CODE ====

// read in
tic
mydat = csvRead('dat04-2011.csv', ';', ',', 'double', [], [], [], 6);
toc (= 5,213 secs)
mydat = mydat(:,2:6);
tic
mystring = csvRead('dat04-2011.csv', ';', ',', 'string', [], [], [], 6);
toc (= 3,077 secs)
mystring = mystring(:,1);


tic
for i=1:size(mydat,1)
    mydate(i,:) = strtod(strsplit(mystring(i,1),['.';' ';':']))';
end
toc (= 186,473 secs)


==== CODE ====
(I filled in the toc values).


As you can see this is unfortunately very slow. The read in of the csv, but 
especially the for loop.

So I have several question:

1)
Is there a faster way to read in the csv? Note that I need the 'header' 
option.

2)
Instead of the loop I would like to use
mydate = strtod(strsplit(mystring(:,1),['.';' ';':']))';
but this doesn't work. Is there another way to avoid the loop?

3)
The raw csv file is around 15MB, but when I want to read it in the second 
time, Scilab says this will exceed the stacksize. Which is default by 76MB. 
So I don't quite understand how two times the 15MB file takes so much 
memory? I raised the stacksize now, but I would rather like not to.


Any help is appreciated.
Thanks!
Richard

Hi

The code you provide does not run on my sci 5.5.0

anyway, i would read only the once the matrix, as a string, and then use 
csvTextScan on

mydat(:,2:6)

to convert that part to double. Taht already saves time.

in your loop i believe strtod is extremely slow. Again, use csvtextscan 
instead.

Hope this helps

Adrien

Thanks for your help.

It's a good idea but block->work is already used.

I think i'll use another solution suggested by Serge in developers mailing.
Import.h allow me to read block->work of all the blocks of my diagram.
I'll be easier for me.

Paul,

I am afraid i do not catch it... Could you be a bit more explicit? Are 
you speaking about inner ticks?

Hello Adrien,

You may use the "data field :)

xstring(1,1,"Hello")
the_string = gce();
the_string.data  =  [1,2] // new position

Nope

The areas make the axes invisible, as if the axes were dranw first, and 
the area painted after.
Curretly I work around this by plotting my area starting a (0.01, 0.01) 
instead of (0,0)

See how the gree area makes the x axis invisible.
inner tics would be invisible also

I just checked the help page

http://help.scilab.org/docs/5.3.3/en_US/xstringl.html

The last example deals with strings in LaTeX format.

Does this help?

Actually i'd like to know if in the following the  "2" stands for "I am 
using Latex/MathML" .
Calixte?

str=["SCILAB","can write LaTeX :","$\frac{abc}{xyz}$";"or","MathML :",mathml]  ;  
r2  =  xstringl(0.5,0.5,str,2,5)

the "2" stands for the font ID...hence you should be able to change
font style by entering a different number there..see the help page

The $-sign in the str = (...) defines that the string is drawn in LaTeX mode.

note that there are at least two modes to write LaTeX

- a text mode
- a math mode

using just  the $-sign will enable LaTeX format but in math mode.
hence white space won't be drawn


using "$\mbox{}$" enables LaTeX mode (the $-sign), but now everything
that is written in between the brackets of \mbox{} is written in text
mode...hence white space is also drawn.


You may try following example code:
As you may recognize I used the gce() command to change the font style.
I do this because changing the font style within xstringl() somehow
doesn't work for me.




plot2d([0;1],[0;1],0);
// Only valid from Scilab 5.2

str1=["simple text"] ;

str2=["$\mbox{LaTeX format in text mode}$" ; "" ; "" ; "$LaTeX format
in mathmode$"] ;


r1 = xstringl(0.1,0.1,str1,2,4);
r2 = xstringl(0.1,0.4,str2);

xrects([r1(1) r1(2)+r1(4) r1(3) r1(4)]');       // computes rectangle
around string
xstring(r1(1),r1(2),str1);

xrects([r2(1) r2(2)+r2(4) r2(3) r2(4)]');       // computes rectangle
around string
xstring(r2(1),r2(2),str2);

// use just xstring

xstring(0.5,0.2,str2,0,1);       // computes as well rectangle around
string, since angle = 0 deg
xstring(0.5,0.5,str2,0,0);      // no rectangle asince bounding box value = 0

xstring(0.5,0.7,str2,-10,1);    // no rectangle around string since
angle = -45deg
e = gce();
e.font_style = 2;
e.font_size = 4;
e.box = 'on' ;

xstring(0.5,0.1,str1);
e = gce();
e.font_style = 2;
e.font_size = 4;
e.box = 'on' ;

Subject: [Scilab-users] Matrix plot using Matplot syntax
Message-ID: <1400818072754-4030568.post@n3.nabble.com>

Hello everyone,

Does anyone knows how to specify the color in Matplot ? I am trying to plot
the matrix using Matplot and my matrix consist of 0 and 1. In Matplot black
color is assigned for both 0 and 1. So, i can not distinguish between 0 and
1 while plotting the matrix.

Your help will be really appreciated.

Thanks 
Javed

Thanks for the reply Eric. It is great to get hints and suggestions from
the author directly!

I used the commands that you outlined, and they were able to reproduce the
expected output verbatim, which is great. Thanks for clearing that up for
me. I've gotten further towards my goal.

I've now got three questions:

1)  I get an unexpected result when I run ms_var() on my own data. I run
these commands:

load('arhmm_example.dat')
nb_states=2
switch_var=2 // variances are switching
var_opt=3 // unrestricted var-cov matrix
r=ms_var('cte',3,'ardata',nb_states,switch_var,var_opt,'prt=initial;final','opt_convg=0')

I receive this output:

WARNING: in overlay, series number 2 has been ignored because of a bad
frequency
 !--error 10000
series ends before the end date of the bounds
at line      39 of function ts2vec0 called by :
at line     101 of function explone called by :
at line     253 of function ms_var called by :
r=ms_var('cte',3,'ardata',nb_states,switch_var,var_opt,'prt=initial;final','opt_convg=0')

The arhmm_example.dat file is available here[0], and it was made by
running.the following command on the original csv[1] file arhmm_example.csv.

impexc2bd('arhmm_example.csv', ';', 'arhmm_example.dat')

I believe I either don't have the dates configured correctly, or it
requires a specific number of data points to match the frequency value,
which also may be wrong. Do you have some insight into this error message?
I've been reading the docs on the ts structure, and I will continue to try
to solve this roadblock.


2) My goal in doing all this is to analyze Autoregressive Hidden Markov
Models. As I understand it, the VAR-HMM that ms_var provides is a
multivariate case of an Autoregressive Hidden Markov Model. The terms
Markov Switching Model, and Hidden Markov Model refer to the same thing.
Using a single variable with ms_var() as I show above in the example, will
simulate an AR-HMM(3). I would like to check if these statements agree with
your understanding.


3) How could I contribute to the grocer code. At the very least I could
improve the docs some.

Dear Brian

1) For me it works fine; I suspect that you have run ms_var with your data
after having run with the manual example. I expect that if you reopen
Scialb and run your problem, starting from load('arhmm_example.dat'), it
will work. A good advice anyway is to set the bounds before each estimation
or to run:
--> bounds()
if you want to use the greatest available time span with your data
2) I agree; indeed the example in the manual as well as yours are
univariate, but ms_var also works with multivariate series (I have run some
tests which worked well)
3) If you want to contribute, do not hesitate to send me code (at
grocer.toolbox at gmail.com or grocer.toolbox at free.fr); add your copyright; if
you can create a help file it would still be better (I have some tools do
help doing that if you want them); and if you can add to the manual, it
would be marvellous!
If you want to imporve the docs you are also welcome; I can sned you the
OpenOffice files you need if you find it suitable

?ric.

 Hello, I opened to new topic in scilab mailing lists to get a little problem straightened out, but for some reason it had subscribed me to many different irrelevant topic and I'm getting emails from all of them (over 50 in less than a week)
Can you please take my email off ANY subscription list?
I'm really sorry for the inconvenienceThanks in advance

Hello,
I have noticed in Xubuntu Linux that, after Scilab stopped working and 
I had to stop it by clicking the close button of the console window 
(the menu did not work), I could still see scilab-bin in top (which 
shows all running programs).

Hi there

A colleague of mine cannot write Scilab code yet, so he writes in Matlab 
and I convert. So far I've run into a couple of issues that I don't know 
what to make of. Please help us. The .sce script file is attached.

1) The "plot" which is commented out on line 41 crashes Scilab. I wonder 
why - is it because I'm plotting 24000 data points?

2) At the end of the script (line 111) I get a memory allocation error 
with "conv" ... please help on this one.

P.S. My colleague is trying to generate IEC 268-1 noise ... later to 
compress it and make IEC 268-5 (EN 60268-5) test signal for power 
testing loudspeakers.

/Claus

Hello,

I just tried your code and it works for me. The plot did not crash 
Scilab. I had to change something - instead of using conv() I ised 
convol(). Previously I had to increase the stack size with 
stacksize('max'). One more thing, trapz() should be changed to inttrap()

I do not know if this is correct - just tried to see if this would work. 
(Scilab 5.5.0)

Regards,
Radovan

Hi Radovan

Thanks for the help. I changed stacksize, I use convol and it works 
(Scilab 5.5.0). Also thank you for looking ahead - I'll change trapz to 
inttrap.

Also thanks to Raghu Char for identifying the stacksize problem. My 
error message was on Memory allocation (slightly different).

/Claus

Subject: [Scilab-users] tic toc time
Message-ID: <5381C41B.40907@gmail.com>

Hi there

Converting from matlab to scilab is finished, but the matlab code 
contains a tic toc (begin/end of script timer).

The Scilab code doesn't display anything.

I thought I'd go like this (based on example from the Scilab manual):

tic();
realtimeinit(1);
realtime(0);
realtime(10);
t = toc;
printf("Time (tic-toc) %f \n",t);

That doesn't work.

How do I make Scilab display the registered time ???

/Claus

Hi Paul

You're right <blush> - a very basic error.

Dear Manager,
(If you are not the person who is in charge of this, please forward this to your CEO,Thanks)
This email is from China domain name registration center, which mainly deal with the domain name registration and dispute internationally in China.
We received an application from Huahong Ltd on May 20, 2014. They want to register " scilab " as their Internet Keyword and " scilab .cn "?" scilab .com.cn " ?" scilab .net.cn "?" scilab .org.cn " domain names etc.., they are in China domain names. But after checking it, we find " scilab " conflicts with your company. In order to deal with this matter better, so we send you email and confirm whether this company is your distributor or business partner in China or not? 
Best Regards, 
Jim

Hello,
While trying to compute pairwise distances between random points, I have 
come across
a behavior of function find() that I don't understand. I do the following:

// initialisation
diam = 0.2;
nd = 10;
etat = (rand(nd,2) -0.5)*4;
distance = zeros(nd,nd);
//compute distance matrix
for i = 1:(nd-1)
     for j = (i+1):nd
         distance(i,j) = 
sqrt((etat(i,1)-etat(j,1))**2+(etat(i,2)-etat(j,2)**2));
     end
end
//find close pairs
[li,lj] = find(distance<diam)

With both Scilab 5.4.1 and Scilab 5.5, the last line raises the error 
message:
                          !--error 144
Op?ration non d?finie pour les op?randes donn?es.

I will be grateful to anybody who spots my error.

Thank your for your time,
JP Grivet

Hi,

You are computing "operator<" over complex number (which is not defined) 
because your distance matrix has an error

Try with this change
distance(i,j) = sqrt((etat(i,1)-etat(j,1))**2+(etat(i,2)-etat(j,2)**2));
=>
distance(i,j) = sqrt((etat(i,1)-etat(j,1))**2+(etat(i,2)-etat(j,2))**2);

Full script:
// initialisation
diam = 0.2;
nd = 10;
etat = (rand(nd,2) -0.5)*4;
distance = zeros(nd,nd);
//compute distance matrix
for i = 1:(nd-1)
     for j = (i+1):nd
         distance(i,j) = 
sqrt((etat(i,1)-etat(j,1))**2+(etat(i,2)-etat(j,2))**2);
     end
end
//find close pairs
[li,lj] = find(distance<diam)

Best,

Hello, 

Appart from the parenthetis error pointed out by Pierre-Aim?,
something imho a bit more efficient: 

distance(i,j) = norm([etat(i, :) - etat(j, :)])

Best regards

I have a suggestion related to my previous post concerning pairwise
distances. I have just learned the Matlab provides a function, pdist,
that computes these in a single instruction: pdist(M). it would be
convenient if the same functionwere implemented in Scilab.

Hi all; 

@JP Grivet: The following manual can guide you how to write own Scilab
function for distance computations. 
http://docs.scipy.org/doc/scipy-0.13.0/reference/generated/scipy.spatial.distance.pdist.html

Moreover, there are two statistics toolboxes which provide what you need.
Please see the links below. 

@Pierre-Aim? Agnel: There are two Scilab function which do the same task as
Matlab one.
nan_pdist() from NaN toolbox (Please see:
https://atoms.scilab.org/toolboxes/nan)
scidoe_pdist() from Scidoe toolbox
(https://atoms.scilab.org/toolboxes/scidoe)

Regards, 
Mehran

You may do without explicit nested loops:

[X,Y] = meshgrid(etat(:,1), etat(:,2));
distance = sqrt((X-X.').^2 + (Y-Y.').^2)

Thank you all for your suggestions concerning pair-wise distances. The 
motivation behind my
question is that I am writing a simplistic molecular dynamics program, 
where hard disks move
freely inside a plane region, except when colliding with boudaries or 
with other disks. I hoped
that my program could be as fast as the beautiful Python program of Jake 
Vanderplas
(http://jakevdp.github.com) but, up to now, the Python code is still 
significantly faster.

Thank you, Samuel. I have made a comment to your bug report.

Another question:
Is it possible to get rid of the extra title bar in a figure? It just 
repeats the text in the main title bar and makes the axes space lower, 
to no avail whatsoever.

Message-ID: <5386FD0F.2080600@teikav.edu.gr>

Hi all,

I currently added support for cooperating with SciLab from the GroovyLab 
project
https://code.google.com/p/jlabgroovy/wiki/SciLabInGroovyLab?ts=1401355143&updated=SciLabInGroovyLab
and it seems interested,
SciLab build-in operations as svd, are really fast!


To anyone interested SciLab, the version of GroovyLab that can cooperate 
with SciLab
can be found in
https://sourceforge.net/projects/groovylab/


Looking forward for feedback and improvements hints!


... and:  SciLab runs on OpenSuSE 13.1?
It runs on OpenSUSE 12.2, but it seems to have a problem in execute time 
in 13.1


Best Regards
Stergios

Hi Eric,

Thanks again for the response. What you told me to do worked. If I closed
Scilab, and rerun the example from my earlier e-mail, I do not see any
warnings, which is good. The output I received is not what I expected in
several ways, so I'll ask some more questions here. There are a lot of
different questions here, but they all relate to the example below, and the
use of ms_var and GROCER. Thanks in advance for any insight into the issues
I am experiencing.

The example:

I have a file arhmm_example_280.dat [0] that was generated and loaded
from arhmm_example_280.csv [1] using the following commands:

    impexc2bd('arhmm_example_280.csv', ';', 'arhmm_example_280.dat')
    load('arhmm_example_280.dat')

I then run, what I expect to be a single variable, 2-regime,

    nb_states=2
    switch_var=2
    var_opt=3

  r=ms_var('cte',3,'ardata',nb_states,switch_var,var_opt,'prt=initial;final','opt_convg=0')

I then receive this output:      http://ur1.ca/hej98

1) In the "coefficients" section of the output, the output doesn't seem to
contain enough numbers to describe the expected number of outputs. The
model has 2 regimes, and it is autoregressive with order 3, so I expect
there to be 3 coefficients for EACH regime (regime 1 and regime 2).
Instead, I see a single coefficient for Regime 1 (0.9313736) and a single
coefficient for Regime 2 (8.2685973). Where are the three autoregressive
parameters for regime 1 and the other three autoregressive parameters for
regime 2?

2) There is a section in the output called "All Regimes" which is in the
"Coefficients" section contains 3 coefficients. Do these correspond to the
autoregressive aspect of the model [0.2258037, 0.4757391, -0.3161730). I
expected to see a section like this for Regime 1, and one for Regime 2, but
I did not. I'm not sure how these 3 coefficients for "All Regimes" fit in.
The Markov Switching Model switches the autoregressive coefficients with
each Regime, so I'm not sure how to interpret coefficients that are for
"both regimes".

3) I believe each regime will have its error term estimated, and I do see
that in the output. For example under Regime 2, the variance of the error
term is 2.3164941. This is listed in the section "Variance-covariance
matrix of residuals" which is a subsection under "Regime 2". Am I
interpreting the output correctly? Where is the mean value for the regime?

4)  My overall goal is to validate that I can hand a list of observations
to GROCER+scilab, along with the order of the autoregressive model, and the
number of regimes, and have it estimate the Markov hidden state transition
probabilities, the estimated regime that is in effect at time t, and
coefficients for each regime, and the error term that can be used for
prediction of the t+1 observation. I don't know of a "well known" data set
that allows for this type of validation, so I wrote a simple AR-HMM
generator named koa marhn [2], which outputs AR-HMM data that follows a set
of parameters. This is the program that generated the 280 point data set in
the arhmm_example_280.csv [1] file. You can see the parameters used to
generate this file here:

    https://github.com/bmbouter/koa_marhn/blob/master/arhmm_example.py

A[i][j] is the probability transition from regime i to regime j.
C[x][y] is the autoregressive coefficient for regime x used for generation
of the t+1 element from the t, t-1, t-2, ..., t-y summation. Each y is a
coefficient for regime x.
R[q] contains mean and std_deviation values for regime q
pi[m] contains the starting state probabilities that the regime is in state
m at time t=0

The output from http://ur1.ca/hej98 does not correspond at all with the
values of these inputs, which means something unexpected is going on! Do
you have insight into why scilab doesn't produce these expected numbers?

5)  One possibility is that maybe it is "working", but there isn't enough
data for it to estimate the parameters correctly. I had koa marhn [2]
output 10,000 observations, but I ran into trouble transforming it from a
csv file to a dat file using impexc2bd. My input file is
arhmm_example_10000.csv [3]. I tried to convert to .dat using:

    impexc2bd('arhmm_example_10000.csv', ';', 'arhmm_example_10000.dat')

I receive this output, and the .dat file in NOT created

 !--error 10000
dates are entered neither in chronlogical order nor in reverseerse
chronological order
at line      87 of function read_dates called by :
at line     188 of function impexc2bd called by :
arhmm_example_10000.dat'

How do you transform a large .csv file to .dat? Is there some problem with
the data file, the way I am making it?

This e-mail is way to long, but I wanted to fully recap the issues I've
considered as I use ms_var(). Thanks for any help you can provide. You can
also find me in the #scilab channel on the OFTC IRC servers.

Thanks,

Hello Brian

You did not recover the intial parameters because you did not estimate the
same model as the one you generated.

This is because you used in ms_var the option 'cte' which means that only
the constant is allowed to switch: and this is why the AR coeffcients are
only given for 'all regimes'. I f you rather use the option 'all', then all
parameters are allowed to switch and the result is now consistent with the
parameters of the generated model, that is the true values are within the
confidence interval of the estimated ones. This is explained in the help
command (see help ms_var): may I ask you why you did not infer it from the
help files?

As for the big file, I suspect it is truncated into Scilab. Can you try
with data in column instead of in rows?

?ric.

Hello

I am having problems with a program regarding the color detection and
location of that particular color in the picture. I browsed through many
tutorials but was unable to put it into effect for the desired output of
mine. Basically i want to locate the red points in the attached image and
also find the distance between the red and green parts of the image using a
scilab program.

So can u please send me the commands and instructions regarding how i can
proceed through this as i m new to scilab, asap and oblige.

Thank you Povy!

Yes, with Yast2, the binary of SciLab is installed on OpenSuse 13.1.

Only, the direct unzipping of the binary does not work,
probably something happens with the dynamic link libraries, that should 
be placed in
accessible paths.

Hello, can't find what did wrong.

theta calculating perfectly, but last two (rho and tau) getting only one
result, and even doubt that it's correct. Seems need to add data in other
way. Could someone help me to understand my mistake?

Thank you

Hi,

You need to add a "." to the "/" operator to make the calculation 
element-wise:

eps0=8.854e-12;
mu0=1.256e-6;
eps=4*eps0;
mu=4*mu0;

zb1=sqrt(mu0/eps0);
zb2=sqrt(mu/eps);
phi=[0:15:90];

theta=asind(((sqrt(eps0*mu0))/sqrt(eps*mu))*sind(phi));
rho=-((zb1*cosd(theta)-zb2*cosd(phi))./(zb1*cosd(theta)+zb2*cosd(phi)));
tau=(2*zb2*cosd(phi))./(zb1*cosd(theta)+zb2*cosd(phi));

See http://help.scilab.org/docs/5.5.0/en_US/slash.html for more info.

Regards,
Paul

Subject: [Scilab-users] How to get SIVP working with Scilab on the Mac?
Message-ID: <1401538032926-4030634.post@n3.nabble.com>

I may have put this on the wrong list originally, perhaps someone here can
help? 

atoms has SIVP on Windows but not on Mac for some reason.  

Trying to go through the steps to install SIVP is not working for me on the
mac.  

You need opencv to compile SIVP.
If you install opencv with macports, you get the following error

ilib_compile: An error occurred during the compilation:
In file included from camshift.c:20:
In file included from ./common.h:45:
In file included from /opt/local/include/opencv/cvaux.h:54:
/opt/local/include/opencv2/video/background_segm.hpp:47:10: fatal error:
'list' file not found
#include <list>
         ^

What you see above is the result of running exec('builder.sce') in the sivp
directory in Scilab.

I have searched the web for this problem and found a couple of references
but no solution yet.  

If you don't use macports to install opencv and use cmake, Scilab won't
locate it in the default directory which is /usr/local/bin lib, etc.  

Then you just get a message about how you need to install opencv.

If anyone knows how to enjoy the SIVP experience on the Mac, I'd love to
know.

Many Thanks,
Michael

Subject: [Scilab-users] Help write simple GUI
Message-ID: <538A34FD.1050505@gmail.com>

Hi there

I hope someone can help me make a simple GUI front end to my script, 
preferably without using GUI Builder or guimaker, because I think I'll 
understand better without using additional tools.

The GUI - a window containing two variable input:
1. text + input box + text
    Again the input is a number, typically an integer (as in "system 
power : 100 Watt"). 100 being the user variable input.
2. text + input box + text
    A number, typically an intereger (as in "impedance : 8 ohm"). 8 
being the user variable input.

The script will then based on 100 Watt into 8 ohm calculate the voltage 
= sqrt(100*8). I will round the number to one decimal, convert it to a 
string and create an answer, like "Input level : 28.3 Volt".

The GUI should contain two buttons, e.g. an OK + a QUIT button. The OK 
button runs the calculations. The quit button quits the script (may as 
well quit Scilab).

I've studied the GUI controls in Scilab already and I understand the the 
old way of making a new window is:

f = figure();

but it seems there's a new command in Scilab 5.5.0:

f = createWindow();

The new method probably has its advantages, but the Scilab manual 
doesn't really explain... can anybody explain to me?

Can you use the same uicontrol commands with both methods? (can I use 
examples found on the internet using "figure" and just replace figure 
with createWindow?). It seems to me that the examples in the 
createWindow gives uicontrol some inputs named "units" - "normalized" - 
etc. - which are not present when looking at old figure() examples.

My next question will be, how do I create a uicontrol which accepts a 
string input (as I need 2 of those). The uicontrol documentation says 
the "Edit" style will do that. Funny, but also a bit strange, that you 
can find all sorts of examples for using uicontrol with checboxes, 
listboxes, radiobuttons, pushbuttons, tables etc. - but no examples are 
provided with this most useful editable string input ... (???)

... hereafter I expect to evaluate the two strings (or if they're 
returned as numbers, that's fine of course, I just don't need the script 
to crash if something is not right). Then execute my code.

Best regards,
Claus
