Hi Germaingondor:

Well I have both 64-bit 5.3.3 and 5.4.0 installed on a legit Windows 7 Home
Premium on a i7-3610QM Intel CPU Laptop and ls and dir works. Have you did
a clean install? Have you activated your Windows OS?

Regards,

Dr.Bernz

Thanks for your answer !

I've solved my problem by removing the clear() function at the begining of my program.

If clear() is writen, ls and dir don't work.

Thank you and...happy new year !

Best Regards,

Dr Gondor

Message-ID: <3B5FFC67498DFF49AE7271A584867D16F10604D652@301EX00100.sidel.com>

Hello,

I'm starting with my first graphical user interfaces.
It seems OK until I try to encapsulate it into a function.

Here is a minimal complete example:

// **********
function []=test(h)
    text = uicontrol(h, "style", "edit", ...
        "string", "foo",...
        "position", [50 100 100 20]);
    bouton = uicontrol(h, "string", "OK",...
        "position", [50 50 50 20], ...
        "callback", "text.string = string(0);");
endfunction

fig = figure(0);
test(fig);
// **********

When I run the script, nothing happens.

And if I first run execute the script without encapsulation
then the script with encapsulation (without clear() inbetween),
I get
  !--error 999 
set : The handle is no more valid.
at line       4 of function generic_i_h called by :  
at line       2 of function %c_i_h called by :  
bject(251);text.string = string(0);;if exists("%oldgcbo") then gcbo 
while executing a callback

So, I can I encapsulate?

You must modify your test function as given below, because  the test 
function creates the widgets and then exits, so when you click on the ok 
button the text variable is no more defined.
The solution below saves the texte handle into the userdata field of the 
control bouton data structure so it can be retreived by gcbo.userdata by 
the callback.

function []=test(h)
     text = uicontrol(h, "style", "edit", ...
         "string", "foo",...
         "position", [50 100 100 20]);
     bouton = uicontrol(h, "string", "OK",...
         "position", [50 50 50 20], ...
         "userdata",text,...
         "callback", "gcbo.userdata.string = string(0);");
endfunction

fig = figure(0);
test(fig);

Message-ID: <1357146862213-4025606.post@n3.nabble.com>

How to develop a Scilab-java application using apache-ant/apache-maven?

Let us consider the following sample:
import org.scilab.modules.javasci.Scilab;
import org.scilab.modules.types.ScilabType;
import org.scilab.modules.types.ScilabDouble;

public class  TstJavaSci1{
  public static void main(String[] args){
    try{
      Scilab sci=new Scilab();
      if(sci.open()){       
        sci.exec(new String[]{"u=1","v=u+1","disp(v)"});
        sci.close();
      }
      else{
        System.out.println("Could not start Scilab ");
      }
    } 
    catch(org.scilab.modules.javasci.JavasciException e) {
      System.err.println("An exception occured: " +
e.getLocalizedMessage());
    }
  }
}
The execution may be carried out successfully with the following script
(Windows)
set SCILAB_HOME=c:\Program Files\scilab-5.4.0
set
SCILAB_PATH=%SCILAB_HOME%\modules\javasci\jar\org.scilab.modules.javasci.jar;%SCILAB_HOME%\modules\types\jar\org.scilab.modules.types.jar
set classpath=build;%SCILAB_PATH%;

rm build
md build
javac -d build src\TstJavaSci1.java
java TstJavaSci1
set SCILAB_HOME=c:\Program Files\scilab-5.4.0
set
SCILAB_PATH=%SCILAB_HOME%\modules\javasci\jar\org.scilab.modules.javasci.jar;%SCILAB_HOME%\modules\types\jar\org.scilab.modules.types.jar
set classpath=build;%SCILAB_PATH%;

rm build
md build
javac -d build src\TstJavaSci1.java
java TstJavaSci1
But if I tried to run with the apache-ant with the build.xml file
<?xml version='1.0' encoding='UTF-8'?>

</project>
I get the following errors

The PATH of the system contains the reference ?C:\Program

The same errors are obtained using apache-maven.

ASY.Pr.NAME = Samy

ASY.Pr.REKE = XY

ASY.Pr.LOG

and give it as a tlist in scilab for example
tlist(['Pr,'VER','NAME','REKE','LOG'],2.0,Samy, XY)

it's possible? 

i have a large file

I thank you in advance for any help.

This is documented here:

Basically, this usually means that you have not set up the PATH variable
correctly.

It would be easy if your file contained something like
ASY.Pr.VER = 2.0

ASY.Pr.NAME = "Samy"

ASY.Pr.REKE = "XY"

ASY.Pr.LOG=[]
Because in such a case you may have only to exec it.

If you cannot produce such a file  maybe you can proceed as follow
*
**digits=string(0:9);**
**txt=stripblanks(mgetl('your file'));**
**txt(txt=='')=[]; //remove blank lines**
**n=size(txt,1); //the number of lines**
**I=[];**
**for k=1:n**
** t=tokens(txt(k),"=");**
** if size(t,'*')==2 then**
**   t2=stripblanks(t(2));**
**   if or(part(t2,1)==digits) then**
**     I=[I;txt(k)];**
**   else**
**     I=[I;t(1)+"="""+t2+""""];**
**   end**
** else**
**   I=[I;txt(k)+"=[]"];**
** end**
**end**
**clear ASY**
**execstr(I)**
**//here ASY is a struct with one field named Pr and ASY.Pr is a struct**
**ASY.Pr**
*

Subject: [Scilab-users] parallel_run on linux with 8 cores problem with
	nb_workers
Message-ID: <1357242919791-4025610.post@n3.nabble.com>

Hi all,

Did any one can explain why example from scilab help are executed only once?
function a=g(arg1)
disp("called on "+string(arg1));
  a=arg1*arg1;
disp("computed "+string(a));
endfunction
res=parallel_run(1:6, g);

If i change to parallel_run(1:24,g) execution occure only 3 times.

Situation is changed only if i set 'nb_workers' to 8 - then it work on all
cores, and when i set it to 1, the it work only on 1 core.

Regarding to help, default  value should be 0 and it should mean to use all
cores i have in system. Behaviour is same even if i manually set nb_workers
to 0.

(Now i know solution, But i don't know reason of it, is it a problem with my
instalation ort system or mistake in help. I decide to place here this post
becouse maybe someone else have similar problem and waste a lot of time for
it liki i have done).

hi

i have a file, myscript.sce

i'd like to call a function inside myscript.sce which would return the 
line in the file myscript.sce where the function is called.
Does that exist?

happy new year

Yes, you might use where() inside the function which calls must be located:

// script testy_foo.sce

function  Ln  =foo()
     b  =  2
     [Ln,F]  =  where()
     Ln  =  Ln($)
endfunction

a  =  1;
disp(foo())

Best wishes for 2013!
Samuel

Subject: [Scilab-users] plot a tree
Message-ID: <CAGgDjFR8G3UGeAuF90Q=LzrXT5Ln4DQ2G8K1_N-s4XX8r65fsA@mail.gmail.com>

Hello and happy new year to all!

I am looking for a graphic function plotting a tree (in the spirit of, but
not nessarily strictly equivalent to, matlab function treeplot).

I have neither found it in Scilab, in St?phane MOTTELET's plotting library,
nor on the web.

Does nevertheless such a function exist?

Thanks!

?ric.

    It would be easy if your file contained
      something like

      ASY.Pr.VER = 2.0

      

      ASY.Pr.NAME = "Samy"

      

      ASY.Pr.REKE = "XY"

      

      ASY.Pr.LOG=[]

      Because in such a case you may have only to exec it.

      

      If you cannot produce such a file  maybe you can proceed as follow

      

      digits=string(0:9);

      txt=stripblanks(mgetl('your file'));

      txt(txt=='')=[]; //remove blank lines

      n=size(txt,1); //the number of lines

      I=[];

      for k=1:n

       t=tokens(txt(k),"=");

       if size(t,'*')==2 then

         t2=stripblanks(t(2));

         if or(part(t2,1)==digits) then

           I=[I;txt(k)];

         else

           I=[I;t(1)+"="""+t2+""""];

         end

       else

         I=[I;txt(k)+"=[]"];

       end

      end

      clear ASY

      execstr(I)

      //here ASY is a struct with one field named Pr and ASY.Pr
        is a struct

      ASY.Pr

thanks serge ,
i have one more question,
i wrote a vb.net application, that give this output from a xml file 
BHCurve=tlist(['BHCurve';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point']);
BHCurve.Point=tlist(['Point';'B';'H'],0,0);
BHCurve.Point=tlist(['Point';'B';'H'],0.05,32);
BHCurve.Point=tlist(['Point';'B';'H'],0.1,55);
BHCurve.Point=tlist(['Point';'B';'H'],0.15,71);
BHCurve.Point=tlist(['Point';'B';'H'],0.2,82);
BHCurve.Point=tlist(['Point';'B';'H'],0.25,90);
BHCurve.Point=tlist(['Point';'B';'H'],0.3,96);
BHCurve.Point=tlist(['Point';'B';'H'],0.35,101.5);

Now i want to make a  a helplist function in scilab, that i can load in vb.net with the exec('Fullpath\function.sci');
for example 
function[]= zlist(argument)
zlist(str);
ztlist = tlist(['Typ';]) // empty tlist
ztlist(1)(2:size(argument(1,2))
finally the output will change 
BHCurve=ztlist(['BHCurve';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point';'Point']);
BHCurve.Point=ztlist(['Point';'B';'H'],0,0);
BHCurve.Point=ztlist(['Point';'B';'H'],0.05,32);
BHCurve.Point=ztlist(['Point';'B';'H'],0.1,55);.........
Can you understand what i want ??
thank you for you help

i want to read a text file with the following Output:

ASY.Pr.VER = 2.0

ASY.Pr.NAME = Samy

ASY.Pr.REKE = XY

ASY.Pr.LOG

and give it as a tlist in scilab for example
tlist(['Pr,'VER','NAME','REKE','LOG'],2.0,Samy, XY)

it's possible? 

i have a large file

I thank you in advance for any help.

Hi,
I want to plot 3D data with reference grid along all X-Y,Y-Z,X-Z planes. 
Is there any function for this or i have to create grids on these planes
explicitly?

You can use the xgrid function or something like
ax=gca();
ax.grid=ones(1,3)*color("lightgray");

Message-ID: <1357743364066-4025634.post@n3.nabble.com>

hi everybody,
i build in vb.net application from a large xml file a tlist which contains
all nodes from xml in form of tlist, because i work with scicoslab and this
canot parse a xml file. now i have a problem i will make a function in
scilab, when i get for example a output like this:
BHCurve=tlist(['BHCurve';'Point';'Point';'Point';'Point';'']);
BHCurve.Point=tlist(['Point';'B';'H'],0,0);
BHCurve.Point=tlist(['Point';'B';'H'],0.05,32);
BHCurve.Point=tlist(['Point';'B';'H'],0.1,55);
i want to have all the points information without manipulating the point i
try it in vb.net with numbers Point1,Point2 but this is not the very fine
solution.
thanks

A tlist with several equal field names will not work as you expect: when you write BHCurve.Point=xxx there is no reason for Scilab to know it has to change the assigned field
is it possible for you to generate something like
BHCurve=tlist(['BHCurve';'Points'],mlist(["Points","B","H"],[],[]));
BHCurve.Points($+1)=[0 0]
BHCurve.Points($+1)=[0.05 32]

If yes you can make such a syntax work by defining
function P=%s_i_Points(i,v,P)
P.B(i)=v(1)
P.H(i)=v(2)
endfunction

Hello everyone (first of all, sorry 4 my poor english), im newbie in scilab.
Im trying to process data, it includes a header and a matrix with numbers,
letters and symbols.  I used Data=fscanfMat(flist(file)) to read the matrix
without the header; but i can read only the first line (and till the 8
column) then I obtain zeros... i have problems with the symbol * and the
letter S. I cant use linux for replace the caracters...  The form of the
data is: 

/Gem Systems GSM-19W 2065231 v7.0 12 IX 2011 M ew3fl.v7o 
/ID 1 file 02survey.wm 04 VII12

I have to replace the S and * for a zero
How can I do it???

Hello all,

I am using Markov Switching Model (MSM) to detect turning points. I can?t
use Bry Boschan or Harding Pagan. I must use MSM. I don?t understand the
manual?s instructions for Grocer. Specifically, I don?t understand all steps
of the routine on grocer. So, I need a routine for MSM on Grocer.

Thank you very much who can help me

You can substitute the "*" using Scilab
t=mgetl('your file');
t=strsubst(strsubst(t," *" ," 0 ")," S "," 0 ")
Le 09/01/2013 22:35, constantina a ?crit :

Dear Eric.

Could be more precise on the model you want to estimate? (The term
"Markov-switching model" is a generic one: you have to define the law of
your data under the regimes as well as the number of regimes you want to
estimate).

Anyway, there is another Scilab toolbox performing Markov-switching models
(HMM), but it does not seem to be maintained. And I think you will not find
other Scilab ressources corresponding to this kind of models.

?ric.

You can also have a look at

help csv_read

which as an optional argument "substitute" designes for these type of 
cases I believe

Dear ?ric,

Thank you for your answer. Specifically, I need estimate a MSM as in
Hamilton (1989), as follows:

  (page 7).

Thank you very much!

Greetings from Argentina!

Sorry, but maybe you could be a little bit more explicit: I have not the
paper immediately available and Hamilton (1989) page 7 does not as such
speak very much...

Thank u so much Serge it works perfect! but i used an specific file , I have
to program an "authomatic" process, and and have some doubts , if you could
help me would be awesome:

==========================================================================

stacksize('max');
clf;clear;
ieee(2);
 //

//READ DATA

exedir=pwd();
//
path=tk_getdir(title='Select your folder with .txt files');
chdir(path);
fpath=strcat(path+"/*.txt");
flist=listfiles(fpath);
nf=max(size(flist));
for ii=1:nf;
      d(1:2,ii)=strsplit(flist(ii),length(fpath)-5);
      dflist(ii)=d(2,ii);
    end;
rep=x_choose(dflist,'Select your file');

In this part the program fails

*t=mgetl('rep'); 
t=strsubst(strsubst(t," *" ," 0 ")," S "," 0 ") 
mputl(t,'rep')
Data=fscanfMat('rep')

 *



If you could help me Ill be so thankful!

Constantina

That?s ok ?ric. Thank you!

I will try to be more specific. In the chapter 23 (Grocer?s Manual) you
wrote about MSM. I need estimate the most general model (ms_reg) and the two
particulars cases: ms_mean and ms_var, for data sent in the first mail...

Excuse me if the consultation is very elemental, but recently I am starting
with Grocer MSM. I think that is a excellent tool for Scilab. Rigth now, I
am investing time to learn .

Thank you very much!

Dear Eric.

I have done my best to make Grocer ms programs use easy (help files, manual
and demos: did you have a look at the ms_reg_d.sci, ms_var_d.sci demos?).

So tell me what you do not understand?

?ric.

You should use dflist(rep) (without quotes) because rep is the index of the selected file
fpath=dflist(rep)
t=mgetl(fpath);
t=strsubst(strsubst(t," *" ," 0 ")," S "," 0 ");
mputl(t,fpath)

I sorry ?ric, this is the routine.

How I can conditioning the var-cov matrix??

To load data, you have many solutions. For time series I recommend to store
your data in a .txt file, transform the dates in a suitable format (that is
1993q1, 1993q2, etc.), set the name of the corresponding column to "dates"
and use impexc2bd (see impexc2bd). And have a look at chapter 5 of the
manual (as well as chapters 1, 2 and 3  which can also be helpful before
starting any econometric estimation).

For the second question, using one of the functions ms_var, ms_reg or
ms_mean indicates that you are estimating a Markov-switching model: there
rare not other steps inovolved!

Lastly, I do not understand what you mean by "conditioning the var-cov
matrix"; if by this, you mean that the var-cov matrix is different
according to the state of the economy, then give as 3rd argument of
function ms_mean of 5th argument of function ms_reg the number of states
you assumes the economy can experience (this is what is done in the example
provided in ms_reg_d() with the instruction :"switch_var=2 // variances are
switching").

?ric.


PS : turnpoints is a subroutine used by the brybos program, therefore not
relevant for Markov-switching estimation

Take the file transformed as joined, store it say in folder c:/gdp and run
unde scilab
-->impexc2bd('c:\gdp\exemple.txt',';','c:\gdp\exemple.dat')

and do not forget to load the database:
--> load('c:\gdp\exemple.dat')

and run:
-->GDP

Hello ?ric, 

I need only one step, because I was able to replicate your example.

I can load the data:

"Dates;LnPBI"
"1993q1;12,2847456986185"
"1993q2;12,3961633542544"
"1993q3;12,3993569016157" .............................. so on.............

Then, I used impexc2bd, and after that, I loaded .dat file. But, I can?t run
LnPBI.

Thank you!

Eric

(is not the complete data, is an example)
My problem is  data1 is longer than data2. With data 1 i have one value of
temperature each 3 seconds, meanwhile in data 2 I have one value of
temperature each half second. 
I have to "cut" the matrixes, they should have the same lenght (because I
need Data2-(Data1-mean(Data1)) , and starts at the comun hour. I dont know
how do it, Any suggest?

The format of the time is for example 072301 (07:23:01)

What if you change the comma in your file into a dot (the dot is the
decimal separator in Scilab)?

?ric.

PS:
1) if you use the file I have sent to you, then LPIB is equivalent to LnPBI
you want to load into Scilab
2) and log(GDP) too!

Dear ?ric, 
I appreciate your great help.

I can load the data!!

I just need the last step. When I run

r=ms_reg('100*lpbi-lagts(2,lpbi))','['100*(lagts(1,lpbi)-lagts(3,lpbi))';'100*(lagts(2,lpbi)-lagts(4,lpbi))';'100*(lagts(3,lpbi)-lagts(5,lpbi))'],'cte',nb_states,switch_var,var_opt,'transf=stud','prt=initial;final')


I have

  !--error 276 
Falta operador, coma o punto y coma. (English: missing operator, comma or
dot and comma)

Thank you!

Best regards 
Eric

Do you have a problem with the resampling algorithm or with the data
handling?

Concerning the algorithm, I suggest you perform a kind of Savitzky-Golay
smoothing of the biggest matrix :

1- define a, say 3rd degree polynomial by regression on a sliding of 5 
points (must be an odd number),

2- keep the value of the polynomial corresponding to the data in the 1st
matrix that lay in the sliding window.

You cannot use the Savitzky-Golay convolution coefficients, as you are
not necessarilly interested in the middle value.

You can have an example of implementation here
http://commons.wikimedia.org/wiki/File:Savitzky-golay_pic_gaussien_bruite.svg
(look at the last solution; the first one uses the convolution
coefficients).

Hope this helps.

Hello,

If I understand correctly, this should do the job
// select rows corresponding at the same (exact) time in col 1 for Data1 and col.8 for Data2
[v,k1,k2]=intersect(Data1(:,1), Data2(:,8));
// Extract the desired values of temperature (in col. 2 for Data1 and col. 4 for Data2)
Temp1=Data1(k1,2);
Temp2=Data2(k2,4);
Disp([v,Temp1,Temp2,Temp2-(Temp1-mean(Temp1))]); // (or mean(Data1), up to you)

It is also possible to interpolate the values of Data2 for the time values in Data1(:,1) with interp1 (cf. Scilab help)

(is not the complete data, is an example) My problem is  data1 is longer than data2. With data 1 i have one value of temperature each 3 seconds, meanwhile in data 2 I have one value of temperature each half second. 
I have to "cut" the matrixes, they should have the same lenght (because I need Data2-(Data1-mean(Data1)) , and starts at the comun hour. I dont know how do it, Any suggest?

The format of the time is for example 072301 (07:23:01)

I'm not familiar with this function, and have a question about the way
it works. I have the feeling that it creates polynomial arcs (splines)
that goes through all the data points, am I right?

If yes, then it is sensitive to noise.

Is there a function that does a smoothing on several data points so you
can reduce the noise?

Best regards

Correction: what I propose is correct from a syntaxical point a view but
nonsensical from an economic one. Run rather:

-->
r=ms_reg('100*(lpbi-lagts(2,lpbi))',['100*(lagts(1,lpbi)-lagts(3,lpbi))';'100*(lagts(2,lpbi)-lagts(4,lpbi))';'100*(lagts(3,lpbi)-lagts(5,lpbi))'],'cte',nb_states,switch_var,var_opt,'transf=stud','prt=initial;final')

Hello Christophe,

Regarding noise, I have the feeling that "lsq_splin" can do a better job than interp1, which just interpolates linearly in its default operation. However, "smooth" might be the best choice for this task.

Regarding "intersect", I considered that the data provided were representative of the case study, and taking into account only EXACT correspondence would - in this particular case - not miss any data.

Cdlt
Denis
PS: last line should have been:
disp([v',Temp1,Temp2,Temp2-(Temp1-mean(Temp1))]);

The example in the description page looks good, I'll try to understand
what they exactly mean by "breakpoints".
But the fact it performs regression is a good point imho.

> "smooth" might be the best choice for this task.

The example that is provided here for smoooth
http://help.scilab.org/docs/5.4.0/en_US/smooth.html
create a smooth line, that goes away from a mean value.

And using the same step for the function (i.e. replacing
0.1 by 10) also increases the amplitude.

Anyway, thanks for your advice.

TcL/Tk cannot be run on Mac OSes.
AFAIK, the Graphical editor GED is being to be rewritten in Java,
in order to get ride of this limitation [1].
So, i am afraid that the solution is either to stay with Mac and be 
patient...
or to go back to Windows or Linux and use GED in it current TcL/Tk release.

Samuel is right. The new implementation should be available with Scilab
5.5.0.

Hello Naasik,

> just to test my logic interlocking and my basic math functions of scilab.

Hello,

If I may give some advice:

> for a=input("select your shape?")
> end

I would simply write
a=input("select your shape?")

> horner(d,x)

horner is to evaluate a polynomial, and you did not define a polynomial
in Scilab sense. When you write

> [d]=(x)

you juste define a matrix -- [...] -- containing d, and say its equal
to x. You should write something like

x = poly(0, 'x')
d = x

meaning that the variable "x" is the polynomial built on the
indeterminate x with the root 0, i.e. P(x) = x,
then d = P(x) ( = x)

When you write

> function e(c)=c^2
> endfunction

You should write it at the beginning of the script, in the following way :

function [y] = e(x)
    y = x^2
endfunction

(here, x is a local variable, not the monomial defined above)
and then use in the main program body

e(c)

or,if you want to use horner, define a polynomial as above

e = x^2
horner(x, c)

(remember x was already defined)

Hope this helps.

If you look for an algorithm,
maybe you should have a look at

Subject: [Scilab-users] Dockable windows
Message-ID: <CAL81uW5S-swDmoSqzOGfEYnoSgE1izN0RQXM1n5FDh+rw_vrxA@mail.gmail.com>

Hi

In MS Windows version of Scilab-5.4.0 (64-bit), Scilab windows don't seem
to be dockable. However the un-dock facility works fine. Actually in my
case, all too well, since I un-docked some of the windows and now I'm
unable to dock them again. Even if I uninstall and install again Scilab,
the Scilab windows maintain the same un-docked appearance. I wonder if
there is some sort of config file with information about windows
dock/undock status that I may change to get the Scilab desktop appearance I
want. Or perhaps there is a better alternative?

Many thanks

Antonio

If inside Scilab you type 
SCIHOME 
You will get the path of the directory where Scilab saves the owner config files.

Subject: [Scilab-users] user experience with moving average
Message-ID: <1358330408892-4025691.post@n3.nabble.com>

Hi,

i've recently used the new function "conv" introduced since 5.4 version :
that's fine and easy to use, for example to apply simple filtering to
experimental data (sample time greater than 1s typically) with (arithmetic)
moving average (like in MS excel, where the use of this feature was quite
intuitiv while prior to 5.4 and conv function it was not so immediate for
people non skilled in signal processing and no simple test case were given
on the web). 

Moving average is a convolution product of the signal with door function
(see  http://fr.wikipedia.org/wiki/Moyenne_mobile
<http://http://fr.wikipedia.org/wiki/Moyenne_mobile>  ). 
Then it's easy with Scilab to compute this moving average and this basic but
common use may be mentionned in the help page for context search.
A=1:10; // experimental data
N=3; //number of samples over which you want to average
B=ones(N,1); // "door function"
C=1/N*conv(A,B); //resulting filtered data : /!\ check the size and
beginning/end of the result  and truncate for your need

David

Hi all,
I have tried the GUI for the bulk conversion of matlab to scilab in a single folder but it does not work. Instead, I tried the following script below but this crashes Scilab! Does anyone have a solution for either problem? I am using Scilab 5.4.0.

// read each .m file and run matfile2sci

host('S:')
cd ("S:\somepath\matlab")

if getos() == 'Windows' then
    filelist=unix_g('dir /B *.m')
else
    filelist=unix_g('ls *.m')
end

n=size(filelist,1);
for i = 1:n,
    outputfile = filelist(i);
    m = length(outputfile);
    outputfile = part(outputfile,1:(m-1))+".conv";
    matfile2sci(filelist(i),outputfile), end;
end;

Thanks,
Richard

Hi All,
I would like to change the background color in Scinotes for Scilab 5.4, but
the only available interface allows me to change only the desktop backgroung
(and cursor) color.
This feature was available in 5.3 version.

As a Scilab user, is there an other way to force the Scinotes background
color?

Thanks for your assistance.

* close Scinotes
* Edit the file SCIHOME\scinotesConfiguration.xml
* Look for the section

<SciNotes>
   <BackgroundColor  default="#FFFFFF"  value="#EEFFFF"/>
   <ForegroundColor  default="#000000"  value="#000000"/>
</SciNotes>

* Change value for backgroundColor
* Save the change
* Restart Scinotes : it should be ok

Subject: [Scilab-users] Puzzling behaviour ignoring 'Invalid index' error
Message-ID: <1358482300090-4025701.post@n3.nabble.com>

Hi,

I'm finding the following behaviour puzzling. When running the following
code that has one typing error 'lambda(t-t_z)' instead of 'lambda*(t-t_z)':

lambda = -0.9;
function exch=e(t,t_z)
        exch = exp(lambda(t-t_z));
endfunction
e(4.999,3)

we get unexpectedly:

-->e(4.999,3)
 ans  =
 
    0.4065697  

This problem happens for other values t < 5. But for e(5.000,3), or other
values t > 5, we get as expected an error message:

-->e(5.000,3)

 !--error 21 
Invalid index.
at line       2 of function e called by :  
e(5.000,3)
at line       7 of exec file called by :    
exec('C:\Users\Anton\AppData\Local\Temp\SCI_TMP_5144_\LOAD_INTO_SCILAB-6477721663385113459.sce',

while executing a callback

Hi

can you rpovide the full code that makes the bug ?

in your example, for instance, t_z is not defined

lambda = lambda(1); after rounding off of index

errors occur therefore for lambda(>=2)  or lambda(<=2)

Sorry, now with typos corrected:

errors occur therefore for lambda(>=2)  or lambda(<1)

Hi All,
    How can I model a control logic involving simple AND OR gates and

configuration available in Xcos to select discrete time simulation? Please
guide me to tutorial page/ demo. I am new to Scilab.

Especially, is there an easy way to convert month names to numbers? Like

Subject: [Scilab-users] Some questions about Scilab Optim function
Message-ID: <1358775183036-4025722.post@n3.nabble.com>

Hello,

I am using Scilab 5.4 Windows7 optim function to find parameters in a
non-linear model to fit experimental data and I have some questions about
the method used in Scilab.

I am running optim with very good results despite a bit slowly, with the
following function call (x is a vector of length 3 in my case):

   [f,xopt]= optim(list(NDcost,costfun,param1,..,paramN),x0)
   ...
   function f = costfun(x,param1,...,paramN)
   ...

The questions I have regarding optim are:

1.  When using the NDcost option to compute numerically the derivatives is
optim using the quasi-Newton method without constraints?

2. Is this NDcost option equivalent in terms of run time and accuracy to
estimating numerically the derivatives with the dedicate Scilab functions
(derivative or numdiff)?

3. Can the NDcost option be run with constraints?

4. How can we have an idea of the accuracy of the parameters estimated by
optim, or at least of the stability of  the solution found?

Thanks in advance and regards,
Rafael Guerra

The NDcost functio is just a way to give optim a function able to compute the cost and/or the gradient. So all optim options are available in this context. The quality and efficiency will depend on the quality of the estimated derivative

Yes

Yes, under the assumption the numericall derivative is precise enough

You can look at the gradient or projected gradient norm

Hi all,

I need help. I was thinging that I understand this, but still not. It not
work as i suppose it should.

Why following example only 3 times call function a(),

-->lines(0);
-->function a=g(arg1)
-->disp("called on "+string(arg1));
-->//for i=1:1000000,
-->  a=arg1*arg1;
-->// end;
-->disp("computed "+string(a));
-->endfunction
-->res=parallel_run(1:24, g, init_param('nb_workers', 8));
 
 called on 1   
 
 computed 1   
 
 called on 2   
 
 computed 4   
 
 called on 3   
 
 computed 9   



...... and following example call it all 24 times:
-->lines(0);
-->function a=g(arg1)
-->disp("called on "+string(arg1));
-->//for i=1:1000000,
-->  a=arg1*arg1;
-->// end;
-->disp("computed "+string(a));
-->endfunction
-->res=parallel_run(1:24, g, init_param('nb_workers', 1));
 
 called on 1   
 
 computed 1   
 
 called on 2

Hi

As far as i know, you cannot. This is because nothing is really compiled 
in scilab. Try for instance the function fun2string(yourfunction), it 
will show the "source code" of your function.

But hey, information and knowledge wants to be free!

It is quite impossible to protect Scilab function source code  because  
Scilab code is open, so it is possible to modify it to be able to trace 
the  operations performed.

I am unable to install Scilab on my Windows 7 workstation (32 bit). I get the

Internal error: Failed to expand Shell folder constant "userdocs"

I have tried downloading the install program to my desktop and running from
the web site with the same results.

Any help would be appreciated. Thanks

Subject: [Scilab-users] Setting up a C compiler in Scilab 5.4.0
Message-ID: <1358932801761-4025736.post@n3.nabble.com>

Hello,I have only just recently started to use Scilab (Win XP SP2, x64). I
have used ATOMS to install COSELICA and managed to create a model with it.
However, when I tried to simulate it, I got the following error message:I
have looked in the documentation on "Supported and compatible compilers" and
have tried setting up lcc-win32 with ATOMS, which seemed to work, but Scilab
still doesn't find a compiler:I also looked at the wiki page  How can I set
up Microsoft Visual Studio 2008/2010 C++ Express Edition for use with Scilab
x64 on 64-bit Windows ?
<http://wiki.scilab.org/How%20can%20I%20set%20up%20Microsoft%20Visual%20Studio%202008/2010%20Express%20Edition%20for%20use%20with%20Scilab%20x64%20on%2064-bit%20Windows%3F>  
and before I ask IT to install MSVC 2010 C++ Express (I don't have admin
rights), is there a way to tell whether I am using a 32-bit or 64-bit
version of Scilab? It is installed in Program Files (x86), so that suggests
to me it is the 32-bit version. In that case, are the instructions on the
wiki page still relevant?Any suggestions welcome.Many thanks in
advance,Arnaud

I have recently installed version 5.4.0 on my 64-bit Windows Pro system. All
attempts to use the resident help system fail. Neither F1 nor typing help in
the console does anything. The Link to Scilab Online Help works fine, but I
can't find any Scilab help files resident on my computer. Neither can I find
this problem in the mailing list archives. What is the problem? Thank you.

Hello,

isoview does not work the way I expect to in a subplot.

E.g. the following script draws an ellipse instead of a circle.

clf;
subplot(2, 1, 1)
theta = linspace(0, 2*%pi, 20);
plot(cos(theta), sin(theta));
a = get('current_axes');
a.isoview = 'on';

How can I get a circle?

Hi Christophe,

We fixed this bug yesterday:
http://gitweb.scilab.org/?p=scilab.git;a=commit;h=7ff0bb9e3b7d7f25cfa5c3d7a06b6c69fac38a79

So the fix will be in a next nightly-built.

Thanks

add either:
a.axes_bounds(3)=0.5
or:
a.axes_bounds(4)=1

you'll get a circle, but you'll also mess up with the subplot layout.

    wdot = [a1*w(1) - a2*w(1)*w(2); b1*w(1)*w(2) - b2*w(1)*w(1)*w(2) -

endfunction

function Jw = Jacobianf(t,w)
    Jw = [a1 - a2*w(2), -a2*w(1); b1*w(2) - 2*b2*w(1)*w(2), b1*w(1) -

> endfunction

"t" is not used in your function.

Apart from this, the line is cut by an end of line,
better use a line break after the semi-colon ";"
or use the continuation points "..."

e.g.

wdot = [a1*w(1) - a2*w(1)*w(2);
b1*w(1)*w(2) - b2*w(1)*w(1)*w(2) - b3*w(2) + b4]

same for the definition of Jw

Hope this helps

Hi

It would be great if you could point me to some documentation for the
Identification Toolbox. Searched Scilab website and googled Scilab
Identification Toolbox but couldn't get any documentation results

Subject: [Scilab-users] Linearizing a model with COSELICA blocks
Message-ID: <1359134768048-4025761.post@n3.nabble.com>

Hi,I am trying to linearize a model that I built using COSELICA blocks in
Scilab 5.4.0. All the COSELICA blocks are encapsulated in a superblock,
which has standard xcos inputs and outputs. I followed the example shown in
the documentation for lincos, but I am getting the following error:Can
anybody help? Is it even possible to linearize a model with COSELICA
blocks?Thanks,Arnaud

Subject: [Scilab-users] modifying a variable changes the value of another
	variable!!!
Message-ID: <1359139369968-4025762.post@n3.nabble.com>

Hello, I am using some iterative algorithm defined as a function in a .sci
file, and I have the following problem: 
the iterations in the algorithm are controlled by a given variable. Now, if
I define another variable, (which DO NOT affect the values of the control
variable nor the way it is calculated) in the function, the number of
iterations to converge changes! What happens is that the value of the
control variable, for some reason, is modified. It is not a very significant
modification, actually the difference is in the order of 10^-15... the
problem is that this difference propagates exponentially as the iterations
advance, and the total number of iterations and the final result (which is
not unique) can be modified drastically!
My question is, why the value of the control variable is modifyied by the
definition a completely independent variable.
I saw this problem in scilab 5.4.0 and 5.2.2.
I also saw a similar, but worse, problem, before with a similar algorithm. I
just added a command "pause" in the function, and this command was even
OUTSIDE the while loop that defined the iterations... and the number of
iterations was modyfied. How can this happen?

Subject: [Scilab-users] Non-linear ODE uder xcos and integration using C
Message-ID: <1359193147790-4025763.post@n3.nabble.com>

Hello all,

I wonder how to do an inegration under xcos. I want to have this
encapsulated within C function which is model function for user-defined
block. Other words I want to create my own model of system. I want to solve
its nonlinear ODE of system.

/example:/

#include "scicos_block4.h"

#define U			((SCSREAL_COP *)GetRealInPortPtrs(blk, 1))
#define Y			((SCSREAL_COP *)GetRealOutPortPtrs(blk, 1))
#define X			((SCSREAL_COP *)GetState(blk))
#define dX			((SCSREAL_COP *)GetDerState(blk))
#define Xk			((SCSREAL_COP *)GetDstate(blk))
#define W           ((SCSREAL_COP *)GetWorkPtrs(blk))
#define G           (GetGPtrs(blk))
#define J           (GetJrootPtrs(blk))
#define M           (GetModePtrs(blk))

void model(scicos_block *blk, int flag)
{
	int i;

	switch (flag)
	{
		case Initialization:
			break;

		case Ending:
			break;
        
		case DerivativeState:

			break;

		case StateUpdate:
			break;

		case OutputUpdate:
            break;

		default:
				break;
	}
}


I am not familiar with scilab/xcos possibilities, I am looking for more
insights and understand how it works. 

Which block to use for this from the palette?
How to add a C function to the block?
How to pass inputs,ouputs,parameters?
Is there simple example (Van Der Pool)?
Possibilities to solve non-linear ODE equation?

Thank you very much for your help!

Best regards,
Peter

Here is a possible solution, including peaks on the borders:

m = rand(6,6)
M = [m(2,:) ; m ; m($-1,:) ];
M = [M(:,2)  M  M(:,$-1)];
pC = M(2:$-1,2:$-1)>M(1:$-2,2:$-1) & M(2:$-1,2:$-1)>M(3:$,2:$-1);
pR = M(2:$-1,2:$-1)>M(2:$-1,1:$-2) & M(2:$-1,2:$-1)>M(2:$-1,3:$);
isPeak = pC & pR
find(isPeak)      // returns linearized indices of peaks
m(~isPeak) = 0 //  to show only peaks

giving:

hello,
I wont to write a little programm like the example below. When I use
 
/function [wert] = in(x(1) , x($));
     wert = intg(x(1),x($),quad);
endfunction;/

(what I want to do!) it does not work. What am I doing wrong?
thanks a lot!

*clear; clc; xdel;

function y = linear(x);
    y = 2*x;
endfunction;

function yy = quad(x);
    yy = (linear(x))^2;
endfunction;

function [wert] = in(x(1) , x($));
     wert = intg(x(1),x($),quad);
endfunction;

x =  [0:4];

wert = intg(x(1) , x($) , quad); //this works*

Hi,

Invalid syntax for the input variable names in: function [wert] = in(x(1) ,
x($)).
Write instead:

   function wert = in(x);
        wert = intg(x(1),x($),quad);
   endfunction;

x =  [0:4];
wert = in(x); //should work now

Hello,

In Scilab 5.4 (Windows 7) if one creates a folder with the command:
   status= createdir('D:\OUTPUT');

and the folder already exists, then a warning message will be issued in
Scilab's Console:
   createdir: Warning: Directory 'D:\OUTPUT' already exists.

How can one check in Scilab if a directory already exists?
How to disable the warning message above?

Thanks and regards,

guy guys

mkdir does what you want

does not issue a warning when the dir already existed, instead returns a 
status that you can ignore:

-->mkdir foo
  ans  =

     1.

-->mkdir foo
  ans  =

     2.

-->mkdir foo
  ans  =

     2.

-->mkdir "this%???$^? wont work"
  ans  =

     0.

help mkdir



kind regards

right, but this turn off all warnings from any command, not only for 
createdir().
This is clearly efficient, but a bit hard ;)
For instance, warnings coming from commands that are turned obsolete should
not be ignored...

When I started Scilab-5.4.0 all appeared to be well:

Startup execution:
  loading initial environment
 -->atomsSetConfig('Verbose','True')
 ans  =
    1.
-->atomsGetConfig()
 ans  =
   downloadTool: "curl"
   Verbose: "True"

The  window Main categories - ATOMS was functional and allowed me to
install say the Plotting library particularly promising to a MATLAB
ex-user --- I get the message:

Installation done! Please restart Scilab to take changes into account.

OK restarting:

Startup execution:
  loading initial environment

Start plotlib toolbox 0.43
Load macros
Load help

  !--error 999
'background' property does not exist for this handle.
at line      46 of function uicontrol called by :
at line     207 of function atomsGui called by :
ms") then atomsGui(); else disp(gettext("
while executing a callback

The error message itself seems garbled!

The next one seems clearer:

-->atomsGui()
 !--error 999
'background' property does not exist for this handle.
at line      46 of function uicontrol called by :
at line     207 of function atomsGui called by :
atomsGui()

The window Main categories - ATOMS  which appears is now empty and
indeed as "dead" as a dodo.

I checked that I have full control over the SCIHOME folder and its contents.

I regularly update the free JAVA which I believe is used by Scilab.

What did I do wrong/missed in installing Scilab-5.4.0?

Any help/info will be appreciated.

Regards,

Ren?.

Thanks Adrien and others for the very helpful responses.

The mkdir function has indeed all the functionality required, seeming more
useful than the more basic createdir function.

Best regards,
Rafael G.

Hello,

It seems that this error is due to plotlib since the error message 
indicates that the error occurred at line 46 of uicontrol and this line 
does not exists in Sciab uicontrol function (which is a C function).

Can you report this issue to the author 
(http://atoms.scilab.org/toolboxes/plotlib)?

Regards.

Hello,

It is possible to linearize a modelica model however I should compile
(in the sense of producing an Xcos block from a modelica diagram) first.

Just define "needcompile=4" before calling lincos and open a
non-documented bug.

Hello, I am using some iterative algorithm defined as a function in a .sci file, and I have the following problem: the iterations in the algorithm are controlled by a given variable. Now, if I define another variable, (which DO NOT affect the values of the control variable nor the way it is calculated) in the function, the number of iterations to converge changes! What happens is that the value of the control variable, for some reason, is modified. It is not a very significant modification, actually the difference is in the order of 10^-15... the problem is that this difference propagates exponentially as the iterations advance, and the total number of iterations and the final result (which is not unique) can be modified drastically!
My question is, why the value of the control variable is modifyied by the definition a completely independent variable. I saw this problem in scilab 5.4.0 and 5.2.2. I also had a similar, but worse, problem, before with a similar algorithm. I just added a command "pause" in the function, and this command was even OUTSIDE the while loop that defined the iterations... and the number of iterations was modyfied. How can this happen?

Maybe you could send us a "minimal" script reproducing the problem?

I recommend you to create a minimal code example which reproduces the
problem you have at hands and to submit it to the users list for evaluation.
It will be easier to help you.

Hello, 

> If I have a vector , por example M= rand(418,1)

Just a question of vocabulary,
are you lookng for peaks with a given width, such as
or for "one-pixel" wide peaks,
which are sometimes refered to as "spikes"?

For spikes, you can use the cade given by Samuel,
just removing the "pC".

If the peaks have a given width,
you can locate the minima of the second derivative,
best after smoothing, e.g.

http://commons.wikimedia.org/wiki/File:Desommation_trois_pics_gaussiens_21pts.svg

The algorithm essentially starts with a set of spheres in random positions
and in a relatively dense state, and runs an iterative process where the
spheres are moved in each iteration in order to reduce the overlaps.
The core of the script is more or less like this


   superp=calc_D_superp_dobcel(pos);  //this line uses an external
function to calculate a matrix with the overlap between paritcles,
defined as superp(i,j)=max(R(i)+R(j)-D(i,j),0) . D(i,j) is the
distance between the spheres and R is the radius. pos is a 3-colum
matrix containging the coordinates of the position of each sphere

    control=0;    //number of
iterationssup_2(int(control/max_mov*20)+1)=sumsupant/max_mov*20;  //
this defines a third control system as will be described bellow. **
while max(superp)>tol  // the maximum value of superp controls when
the system is considered overlap-free and the algorithm is finished

...
// Several lines where the positions of each sphere are modified,
acording to the values of the matrix superp
...

superp=calc_D_superp_dobcel(pos);  //matrix superp is re-calculated
with the new positions

control=control+1;

 if control>max_mov then break; end   // control by maximum number of iterations

//the following belongs to the third control system:

    if length(sup_2)==int(control/max_mov*20) then
sup_2(int(control/max_mov*20)+1)=sum(superp)/max_mov*20;    //**
    else    //**
       sup_2(int(control/max_mov*20)+1)=sup_2(int(control/max_mov*20)+1)
+ sum(superp)/max_mov*20;   //**
   end     //**

  if length(sup_2)>4.5 then    //**
      if sup_2($-1)>0.85*sup_2($-2) & sup_2($-2)>0.85*sup_2($-3) then
break; end     //**
      if sup_2($-1)>0.7*sup_2($-2) & sup_2($-2)>0.7*sup_2($-3) &
sup_2($-3)>0.6*sup_2($-4) then break; end    //**
  end     //**
end     //ends while loop


The third control system essentially controls if the overlap is decreasing
as the iterations proceed. It defines a new variable, sup_2, that stores
the average value of sum(superp) in max_mov/20 iterations. If this average
does not decrease fast enough (>15% decrease in two or >30%decrease in
three consecutive groups of max_mov/20 iterations), it considers that it
will not converge and breaks.
Now, this third control system seems to be problem. As you can see, non of
its lines (marked with ** for more clarity), affects the values of superp
(at least, it shouldn?t). But still, the value of superp is modified when I
include this control system.
The other problem I had was with a similar algorithm, without the third
control system, but just adding a "pause" rigth after the last end. This
will also modify the values of superp and the number of iterations.
As I said, the error in superp is not important (it is in the order of
1.d-15), but this difference propagates exponentially through the
iterations and can significantly modify (like a 30%) the total number of
iterations (I was trying to evaluate if the third control really worked,
but I couldn?t do it because the algortihm CONVERGES with a different
number of iterations...)

yes, you're right, the correct word is "spike".  My problem consist: a matrix
like  [v,k1,k2], the first letter is "time", k1 and k2 are "values" of a
time series.
So... if I plot the values, Im gonna find "spikes" that means "errors,
happens the same with "zero" values... I have to eliminate the wrong values,
and I dont know how to do it, my teacher said that one way is find the
spikes and erase from the matrix, but I dont know how to do it , im newbie
with scilab and I tried with the method of Samuel, but I have problems with 
the size of the matrix (is evident in his example is 6x6) :/ , please any
suggestion?

If the initial position of your sphere are randomly set, it can be 
normal than you do not have the same number of iteration from one 
simulation to an other one.
can you check using
rand("seed",0)
to force identical initial points for your various tests.

Sorry I didn't clarify that: I define the initial random positions, I 
store them in a variable, say pos_in, and then I call the functions (the 
different versions) with pos_in as input, so the initial positions are 
the same in every case.

I reinstalled Scilab and everything works fine now. The new features and
environment in this version are very nice. Thanks to all those who
contributed to its development. As a user only, I am grateful.  Best
regards.

Hi Samuel:

I'd like to understand  the "$" inside the would mean from the script?

Thanks,

It means the last element of the vector/matrix.

This is the size of the object along the related direction:
http://help.scilab.org/docs/5.4.0/en_US/dollar.html

after
a = ones(7,3)
a(:,$)     // is equivalent to a(:,3)
a($-2,:)  // is equivalent to a(5,:)

$ can be used for any type of object: lists, structures, cells,
and obviously matrices and hypermatrices:

L = list("Hello", %pi, (%z-1)^2)
L($)  // returns the polynomial (%z-1)^2 = the last element of L
// To append a element to L, just use(for instance)
L($+1) = %T

$ can also be seen as a measurement of the money that you save when
using Scilab. But this is another undocumented story ;)

>From the code excerpt provided it is difficult to see from where errors of
magnitude~=1e-15 might come from.

Could they be due to some round-off errors in the function:
calc_D_superp_dobcel? Please check the function details.

Have you run the code with a "clear" at the beginning of the program to
clean all variables?

// Could you please define before your 3rd control system:
   superp0= superp;
// and after your 3rd control system:
   superp1= superp;
   printf("%i...delta(superp) = %e", control, max(abs(superp1-superp0)) )
// and tell us what values do you get? Do the errors of 1e-15 magnitude
occur and at which "control" iterations?


// Non related to your problem, herebelow are some suggestions, if you will,
to make your code more easy to read:

   //define additional variables to simplify the code:
   m = int(control/max_mov*20);
   N = length(sup_2);
   s = sum(superp);

   // write:
   while max(superp)>tol & control<=max_mov // moving "control=control+1" to
the end of the while loop


PS: "sumsupant"  // this variable is not defined in the code excerpt, looks
like =sum(superp)


Regards,
Rafael G.

Hello,

> My problem consist: a matrix like  [v,k1,k2]
[...]
> if I plot the values, Im gonna find "spikes" that means "errors

OK, I guess that a spike is a steep change in the value,
a huge derivative.

IMHO, you should compare 2 consecutive values in a column.
This can be done by subtracting
M(i+1, j) - M(i, j) (slope between 2 points)
then compare the absolute value with a given threshold.

Mind that a spike gives 2 consecutive high slopes,
one up and one down.

I suggest:

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

// constants, to be adjusted according to your case
lowerthreshold = 0;
upperthreshold = 3;

// data with spikes

v = [1;2;3;4;10;6;7;8;9;10];
k1 = [1;2;3;4;5;6;7;0;9;10];

M = [v, k1];
disp(M); // display the initial matrix
clf;
plot(M(:,1), M(:,2), 'b-+');

// locate the zeros (or very small values if upperthreshold not 0)
[izeros, jzeros] = find(M <= lowerthreshold);

M(izeros, :) = []; // shrink the lines with zeros
disp(M); // display the matrix without zeros

// Detect the spikes
slope = M(2:$, :) - M(1:$-1,:); // Difference btw consecutive values
k = 0; // initialisation, k is the number of spikes so far
ispikes = []; // in case no spike is detected
for i = 1:size(slope, 'r')
    if abs(slope(i)) >= upperthreshold then
        k = k+1;
        ispikes(k) = i;
        i = i+1 // skip next slope which is also high
    end
end

M(ispikes, :) = [];; // shrink the lines with zeros
disp(M); // display the matrix without spikes
plot(M(:,1), M(:,2), 'r');

Sorry,

I'm not sure the code source was well displayed
(MS Outlook seems to get rid of some carriage return).

Please see the script attached.

Sorry again,

I didn't scope the result with enough attention,

the i = i+1 in for...end loop does not seem to work as I thought it would,
(replaced by a while...end loop)

and I forgot the offset between the indices of the slope and M matrices.

New script attached, should work better.

HTH, regards

One more (rather big) detail,

the script I sent only works when the spike is in the 1st column
(which is the case of the data I use).

please replace

line 22 :
slope = abs(M(2:$, :) - M(1:$-1,:));

line 29 :
    if max(slope(i, :)) >= upperthreshold then

Regards

Subject: [Scilab-users] figure exported before graphical refresh
Message-ID: <3B5FFC67498DFF49AE7271A584867D16F1064B9930@301EX00100.sidel.com>

Hello,

while trying to make an animation,
I noticed that some figures were exported with the wrong scale.

The scale is set by setting the data_bound axes property.

I supposed that the file was created before the scale was set,
so I introduced a sleep(100) and it solved the problem.

Here is a minimal code reproducing the problem;
the image is empty when the scale is not set.

Do I have to report any bug anywhere?

Regards

Hi,

I would say yes, but anyway if you wait ~10 minutes, you'll Get 
Sylvestre answer ;)

By the way, I also experienced this race condition some times ago but I 
did not have time to write a demo to reproduce this bug reliably.

Subject: [Scilab-users] Getting rid of Modelica info pop-up window in Xcos
Message-ID: <1359457860037-4025830.post@n3.nabble.com>

Hi,
I am running an Xcos model which contains some COSELICA blocks. Every time I
run it, the following window pops up:

<http://mailinglists.scilab.org/file/n4025830/modelica_info.jpg> 
This is fine for interactive simulation, but I am trying to run the model
iteratively as part of an optimization routine, which means that I end with
a lot of Java pop-up windows to close. So far, I have limited the amount of
iterations in the optimization to avoid crashing the software with too many
windows, but I would now like to  increase it. Does anybody know to turn
this pop-up window off for scripted simulations, given that COSELICA is
undocumented?
Thanks in advance,
Arnaud

Hi,

I am trying to run scripted simulations of an Xcos model using
scicos_simulate. I have defined the following values:



However, when I run the scicos_simuate command (using scilab 5.4.0), I get
following:



and the response of the model is not what it should be. If I then run the
same model interactively from the Xcos window, I get a completely different
response (the correct one). In the model I have following under Simulation

These variables are also correctly defined in the workspace:



Am I doing anything wrong or is there a bug?

Thanks,

Hi Rafael, thank you for your answer.
I'm running the code with the minimum variables required for it 
(positions, radius, number of spheres).
it can be some sort of error generating in the output (or in some 
internal calculation) of calc_D_superp_dobcel, but I don't think it is 
roundoff, why would that change when defining a different variable or 
adding a command with no connection? superp0 and superp1, as you told me 
to define them, are the same (superp0-superp1=0), so the error is not 
produced in those lines, it is something less direct. I'm not expert, 
but I guess what is happenning here is that, using a section of the RAM, 
the stack, the space where variables are stored, or whatever it is, is 
sligthly modifying OTHER sections of the RAM or wathever. Some bug of 
scilab, or maybe it is a common thing in every program but usually goes 
unnoticed (which would be understandable, it is a 1e-15 error, most of 
the times it will be not significant).
Right after writting this, and remembering some issues like the division 
by zero... I had an idea (is "epiphany" too pretencious?), and I ran it 
on ubuntu... the problem is gone! There is no error under ubuntu. So the 
problem is in Windows (it is Windows server, I can check Windows Vista 
in a few days...). the question is: Is it a Windows bug, or a 
Scilab-for-Windows bug?
By the way, the obvious solution for me would not work. I cannot run my 
simulations in my ubuntu machine, we have the workstation for large 
calculations so we don't overload our personal computers, and the 
worstations runs with Windows server... Well, I can test my control 
system in my ubuntu machine, but not run the real thing...

Subject: [Scilab-users] Simple Date & Time Plotting
Message-ID: <1359480603013-4025833.post@n3.nabble.com>

Hi All,

I would like to find a simple plotting function to enable a plot of numeric
data against *date/time * to be obtained.

I have read numerous workarounds to this problem from input over the years -
usually involving manually manipulating X-Tick Text Data.
I'm just not sure how the graph would show X-axes labels if you zoomed on
into the plot from, say, a 12-month time period right into a 24-hr time
window within it.?
Would I have to run another script to help the plotter out?

In summary:
I would like to plot data Vs Date/Time such that it can automatically
re-adjust the x-axis minor tick marks given the time span when zooming in -
(X-axis in Date-Time format throughout).

Thanks in advance,

Patrick

I'm afraid it is yet not possible with the default zoom tool becausefor 
this behavior it should be necessary to have the possibility to attach a 
callback function that responds to the zoom the resize actions

But you can develop your own zoom menu for zooming time s?ries....

hello scilab users,

 i want to use javasci on NetBeans 6.5 but i have some problems: the output
displays anything when i run the application.

 This is my java code:


import org.scilab.modules.javasci.Scilab;
import org.scilab.modules.types.ScilabType;
import org.scilab.modules.types.ScilabDouble;

public class Example {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
//         TODO code application logic here

        try {
            Scilab sci = new Scilab();
            
            System.out.println("hello world!");

            if (sci.open()) {


            /* Send a Scilab instruction */
            sci.exec("foo = [ 2, 4, 6; 4, 0, 10; 6, 10, 12 ];");

            /* Retrieve the variable foo */
            ScilabType foo = sci.get("foo");

            /* Display the variable */
            System.out.println("Representation of  : "+ foo);
           
            /* Get the data and retrieve the 2,2 value */
            double[][] aReal = ((ScilabDouble)foo).getRealPart();
            System.out.println("foo[1,1] = " + aReal[1][1]);

           /* Change the value of 2,2 */
            aReal[1][1] = Math.PI;

          /* Create a new variable */
            ScilabDouble bar = new ScilabDouble(aReal);

            /* Send it to Scilab */
            sci.put("bar",bar);

           /* Display it through Scilab */
            sci.exec("disp(bar)");

            sci.close();
            } else {
            System.out.println("Could not start Scilab ");
            }


            /* Can be improved by other exceptions: AlreadyRunningException,
            * InitializationException, UndefinedVariableException,
            * UnknownTypeException, etc
            */
            } catch (org.scilab.modules.javasci.JavasciException e) {
            System.err.println("An exception occurred: " +
e.getLocalizedMessage());
            }

    }

}

 the output displays the "hello word" but there are anythings after that!!
(I have no problems when i run the project on the line command)
 So, what is the problems whit Netbans and what should i do?

  I use : 
    - NetBeans 6.5 RC2
    - scilab 5.4.0
    - jre 1.7

  Thank your for your help,

  PS: Sorry for my english!

Thanks for the prompt response Serge,

I'm afraid that type of function would be well beyond me!
Will be interested to see if anyone on the forum has tried to develop something similar in recent times.

Thanks again,

Patrick

Subject: Re: Simple Date & Time Plotting

I'm afraid it is yet not possible with the default zoom tool because for this behavior it should be necessary to have the possibility to attach a callback function that responds to the zoom the resize actions

But you can develop your own zoom menu for zooming time s?ries....

Le 29/01/2013 18:30, Pat a ?crit :

Hi All,



I would like to find a simple plotting function to enable a plot of numeric

data against *date/time * to be obtained.



I have read numerous workarounds to this problem from input over the years -

usually involving manually manipulating X-Tick Text Data.

I'm just not sure how the graph would show X-axes labels if you zoomed on

into the plot from, say, a 12-month time period right into a 24-hr time

window within it.?

Would I have to run another script to help the plotter out?



In summary:

I would like to plot data Vs Date/Time such that it can automatically

re-adjust the x-axis minor tick marks given the time span when zooming in -

(X-axis in Date-Time format throughout).



Thanks in advance,



Patrick

Dear all,

I wonder how to use c_block function under xcos.
Can please help me or point me how to work with this block?
how to define c function, compile it and use it within this block?

Best regards,

Hello,

We can not support 'silent' modelica compilation however some of our
internal non-regression test re-define messagebox to silent any popup
window using the following snip.

--

function btn = messagebox(msg, msgboxtitle, msgboxicon, buttons,
ismodal)
    btn = 0;
endfunction

importXcosDiagram(SCI +
"/modules/xcos/demos/ModelicaBlocks/RLC_Modelica.xcos");
xcos_simulate(scs_m, 4);

Thanks, I have since then switched to a "normal" Xcos model so the problem
has gone away. However, I will definitely try the messagebox function you
suggest if I ever revert to using a COSELICA model.

Subject: [Scilab-users] Same model, different results
Message-ID: <1359646067865-4025848.post@n3.nabble.com>

Hi,Can anybody tell me why the two attached models give different results?
The "first principles" subsystem in the DC_motor_compare model settles to a
steady-state value of 0.61 (red trace), whereas the same subsystem in the
DC_motor_first_principles model goes to 0.95.

I am using Scilab 5.4.0 with lcc-win32 on Windows XP if that makes a
difference. The model DC_motor_compare uses COSELICA blocks.

Thanks,

Arnaud

Hi guys, this my problem data... if I plot one column of data I obtain the
first  plot, and similar case with the second plot... as you can see, theres
two horribles "spikes" in the first plot... and I tried elimite them... but
i cant! i tried with cristophe program, maybe im doing something bad with
the threshold... or so. 
How can indicate in the plot with "dashes lines".... "heeeeere theres a
spike" , or with a circle, the correct location of the spike???

The nearest Scilab package that i know about that would be CGLAB:
http://atoms.scilab.org/toolboxes/cglab
http://atoms.scilab.org/toolboxes/cglab/2.1/filelist/cglab-2.1-1-src.tar.gz
http://cglab.gforge.inria.fr/

but it is not yet extended to support voronoi diagrams.
You may also have a look at the scilab forge:
http://forge.scilab.org/index.php/projects/
