I overlooked, obviously if scipad doesn't start correctly, it might not
create this file at all upon exit.

Though I can't reproduce and I think it is most likely a tcl bug in your
installation, I'll try to figure out and to suggest tests. I'll just
move the discussion to where I feel it belongs more, i.e.
http://bugzilla.scilab.org/show_bug.cgi?id=2879

Usenet is a network of news server. There is no obligation to use Google
for this. Just connect yourself to your ISP news server and you will
have access to Scilab newsgroup (for example, I am using Pan as client
with the internal INRIA newsgroup server).

Subject: System Identification with frfit()
Message-ID: <007401c8af67$7bc88410$1800000a@ibowden>

Bonjour,

I have measured the phase and magnitude response of a system and I am trying
to identify a model for it with frfit(). This works well up to about 10Hz
but then can be 20dB different in gain, 150degrees in phase. Best fit is
with order 3 or 4.

My data is a log frequency sweep from 0.7Hz to 60Hz. It is a little noisy
(+/- 0.5dB, +/-3deg). The response has a 'peak' in the phase between 7 and
20Hz and increasing gain over this region.

I tried separating the model. First I divided the measured data by the
modeled response (to extract just the data that does not fit the model) and
then frfit() to the remaining data. This did not help as the fit to the
remaining data was just as bad.

Can anybody suggest how to analyse this system?

Thanks for any help,

Regards, John

John,
         If you know something about the underlying physics of the 
system, then that is, in my view (as a control and dynamic systems 
person), the place to start.
         I suspect that you can get the peak with a second order 
under damped-pair of poles, and fake the rest of the drop off or rise 
with first order (left half plane) poles and zeros.  It might be 
easier to build a model up from these basic components (as products 
in a transfer function) rather than try to get a mechanical solution 
method. However, it's possible you have a non-minimum phase system so 
it will be trickier.
Mike.

Hi Mike,
Thanks for the suggestion; I'll give it a go. The system should be simple,
it's a DC motor driving a solid load via gears and belts. I think that the
complexity comes from stretching in the belts, lost motion in the gears and
nonlinear effects in the motor, which is why I was looking to identify it
empirically.
Regards, John

John,
         The elastic belt will give a compliance and a means of 
storing energy hence an increase in the order of the system. I see 
the inertia of the motor, the stretch of the belt and the inertia of 
the load  as energy storage elements, maybe an inductance in the 
motor. Each will be a second order component dx/dt and x(t), though 
maybe the belt can be considered a spring of zero inertia. The 
backlash in the gears will create another non-linearity and a 
potential for trouble when you try to get it under control. We could 
always do a simulation and a time domain solution (Scicos).
Mike.

Subject: Problem reading data file using mget
Message-ID: <mailman.3.1676541125.863855.users@lists.scilab.org>

I'm trying to read in a file of 16-bit signed data samples (generated by
a logging system).
 
I try reading in the first 2000 samples using command
    Samples=mget(2000,'s',SampleFileHandle);
 
Problem is that only the first 535 values are read in.
 
Have also tried reading in using
    Samples=mtlb_fread(SampleFileHandle,2000,'int16');
 
If I do this I get an error "...error 10000, End of file reached before
all matrix is read..."
 
If I try to read the same file in using MATLAB and the command
    Samples=fread(SampleFileHandle,2000,'int16');
then it reads in all 2000 values OK.
 
I wonder whether Scilab is misinterpreting one of the data values as an
end-of-file marker, possibly the 536th value since that is where mget
stops. When I read in using MATLAB, it turns out that the 536th element
of Samples array is 26. Is this of special significance?

Subject: min_weight_tree for non oriented graph
Message-ID: <20080510100054.l699oclpq8sco8ww@webmail2.insa-lyon.fr>



   thanks for any help to a newbie, in a learning phase on a simple  
example...? ;o-)

using the min_weight_tree function with a non oriented graph, i do not  
understand the result, and for my understanding, the result is not a  
tree...

before creating a request or bug, i imagine someone can explain more...

Example:

ta=[ 1, 1, 1, 2, 2, 2, 3, 4, 5, 8, 7, 6, 6, 6, 6, 6, 9, 9,10,11,12,13,14];
he=[ 2,10,11, 3, 7, 8, 4, 5, 8, 7, 6,11,12,13,14,15,11,10,11,12,13,14,15];
g=make_graph('name',0,15,ta,he);
t=min_weight_tree(1,g);
for i=1:(node_number(g)-1)
? ? ? ? arbre(i,1)=g.tail(t(i));
? ? ? ? arbre(i,2)=g.head(t(i));
end

-->arbre
arbre? =

? ? 1.? ? ?2.
? ? 2.? ? ?3.
? ? 4.? ? ?5.
? ? 5.? ? ?8.
? ? 6.? ? ?11.
? ? 2.? ? ?7.
? ? 2.? ? ?8.
? ? 9.? ? ?10.
? ? 1.? ? ?10.
? ? 1.? ? ?11.
? ? 11.? ? 12.
? ? 6.? ? ?13.
? ? 6.? ? ?14.
? ? 6.? ? ?15.

For me, in a tree, the root is the only node with no head ...
in this example: 1,4,6,9... that is a forest !

so the result of min_weight_tree is not a tree ?

i read and read again the help with this strange sentence

If  T(I)  is the root of the tree:
- for j < i,  T(J)  is the number of the arc in the tree after node  T(J)
- for j > i,  T(J)  is the number of the arc in the tree before node  T(J)

   t(j) is not a node... so what means "after node  T(J)&QUOT; and   
before node  T(J) ??

   so i suppose there is an error in this documentation...

   again, thanks for any help

Pierre,
         I know nothing at all about minimum weight trees, but I just 
looked at your result as if it was a "net-list" What I see is that 
starting at node 1, all the other nodes are reachable but for 
example, to get to 4 you have to go: 1-2-8-5-4 which means that the 
links 4-5 and 5-8 are traversed in the opposite direction to that in 
which they are listed, but, after all, it's a "non-oriented graph". :-)
Cheers, Mike.
ps: you can actually start anywhere and reach all the other nodes.

Do you know what "minimum spaning tree" is?

The difinition of tree is written in Wikipedia.
http://en.wikipedia.org/wiki/Tree_structure

This case, you have already had a tree.
In tree structure, any node can be root (head) of tree.

many thanks, Yuta,

i was confusing tree and rooted tree..  In my experience (software  
data structures like bill of material)... a tree was supposed to have  
a root...

Hi,

This code can not be used directly in Scilab. You can try to convert it 
using Matlab to Scilab conversion tools embedded in Scilab but these 
tools no yet convert mex files...

Subject: Can not build Scilab with TCL/TK support
Message-ID: <1210875736.16700.2.camel@localhost.localdomain>

I cannot get Scilab to build with TCL/TK support included. I have
compiled and installed both TCL and TK with no problems. But when I try
to build Scilab, I get an error message:

/home/joona/scilab-4.1.2/bin/scilex: error while loading shared
libraries: libtcl8.5.so: cannot open shared object file: No such file or
directory

"locate libtcl" tells me the library is installed
in /usr/local/lib/libtcl8.5.so. Also /usr/local/lib/libtk8.5.so is
there. The configure script finds them but the build process does not.

If I configure Scilab to disable TCL/TK support it builds and starts up
fine but I do not get a TCL GUI.

Can someone help me here?

Message-ID: <33f943660805161356r2afd5ae0i9a00403cc6b8bf4f@mail.gmail.com>

I just started using scilab. In fact I was looking for a code that can
perform minimum weight perfect matching on complete graphs. I am not sure
whether the perfect_match function will do so. I have some confusions that I
need to get cleared about.

1. Why does the arcost vector need to have dimension twice the number of
edges?
2. In the example the vector is generated randomly. But I have a set which
is being generated by another program, hence I have only the costs for the
edges of the graph. If I am doubling the dimension, what values should I be
entering in those slots? For example, if my edge set is "n" dimensional, I
have "n" costs only. But arcost needs to be of dimension "2n". What should
be the values for those "n" additional slots in the vector?
3. I see functions for handling "x" and "y" coordinates of the nodes.
g("node_x") and g("node_y"). What if my dataset is 3 dimensional?

Thanks
Samidh

**** SUNDIALS.Cvode: too much work at time=0.002 (stiff region, change

After few experiments I understood that errors occur due to Delay blocks

The model consists from two parts: setting device and control block.
When I run each part separately they work with no errors.

Bonjour!

Je souhaite tracer un ellipsoide, obtenir un maillage de la surface puis 
un graphe ? partir de ce dernier afin de calculer le plus cours chemin 
entre 2 points.

Etant donn? que pour tracer ce type de surface il faut utiliser 
"eval3dp" afin d'approximer la courbe par des facettes, j'ai essay? de 
r?cup?rer le maillage obtenu.
Mais je me heurte ? un probl?me plut?t g?nant : les coordonn?es d'un 
m?me point ne sont pas toujours exactement les m?mes selon la facette 
sur laquelle on se place...
Par exemple un "m?me point" aura pour coordonn?es (1. , 0. , 0.) ou (1. 
, - 2.445D-16 , 0).

Que faire alors? Je suis tr?s emb?t?s!

Ci-joint au cas o? la fonction que j'ai ?crite pour r?cup?rer les ar?tes 
des facettes g?n?r?es par "eval3dp" pour tracer un ellipsoide.

P.S : je d?bute sous Scilab et je ne connais pas Matlab. J'utilise 
Scilab 4.1.2 sous Linux.

Hi everybody,

I'm using scilab 4.1.2 on a x86_64 box running ubuntu 8.04.

I have trouble with the colorbar function. Each time I try to run the 
function (for instance the example code given in the man page of 
colorbar), I get the following error:
 !--error 999

Does anyone know what's happening and how to fix it?

Any help appreciated.
Best regards,
Mathieu

Thanks for the reply.

Does the bug affect only the x86_64 version of scilab?

I have tried the dirty workaround presented in the bug report without 
success. Do you know which lines I could comment out?

Thanks again.

Subject: negative poly-exponents
Message-ID: <4836BA30.3090708@fhtw-berlin.de>

hello,

I am trying to design discrete filters using the z-transform.
At my university we are doing so in this form:

H(z) = ( (z - z_01) * (z - z_02) ) / ( (z - z_x1) * (z - z_x2) )

of course the result is with positive z-exponents. now: how do I get the 
representation with negative exponents ?

for example:

zo=1.25;
zx=0.8;
z=poly(0,'z');

(z-zo)/(z-zx)
ans =
   - 1.25 + z
     --------
   - 0.8 + z

but I'd like this output:
            -1
   1 - 1.25z
   --------
           -1
   1 - 0.8z


any hints are much appreciated.

Alex

Les coordonn?es d'un m?me point ?tant uniques, il n'y a donc plus 
redondance pour les points et les ar?tes! Ce qui devrait simplifier les 
chose pour cr?er le graphe correspondant dans scilab...

    Sinon j'ai ?crit 2 fonctions "TraceArete" et "TraceEllipsoide" afin 
de v?rifier que je retrouve bien l'ellipsoide dessin? avec "plot3d" pour 
la m?me discr?tisation. Mais j'aimerais savoir comment utiliser des 
couleurs avec la fonction "param3d"? J'aurais en effet besoin de tracer 
par la suite le chemin le plus court entre 2 points!

Merci d'avance pour votre aide!

--------------------- In english :p ------------------

Thank you very much!

The function "clean" solved my problem! My function "MaillageEllipsoide" 
now returns a mesh of my ellipsoide in a matrix without duplicate points 
and arrays.

I wrote 3 functions "TraceArete" and "TraceEllipsoide" in order to check 
if I can redraw my ellipsoide and it works. Nevertheless, I wonder how 
using color with "param3d"... Could you help me on this matter?

You have to uninstalled the SP1 for Vista since it have some problem to run with some dll and some drivers...And reinstall Scilab...try the beta version 5 that works fine...

Message-ID: <483DEBCA.3090502@free.fr>

1) I find a partial answer to my question ;)

In order to use color with "param3d", there are 2 methods (tell me if 
I'm wrong!) :
- 1st method (using "param3d1") :
First, I must get the number corresponding to the color I want using the 
function "color", for example : color("red") returns the number 5.
Then, to draw a red segment between (0,0,0) and (1,1,1) for instance, I 
must type this :
  t=linspace(0,1,p)
  param3d1(t,t,list(t,5.*ones(1,p)))

- 2nd method :
  t=linspace(0,1,p)
  param3d(t,t,t)
  e = gce()
  e.interp_color_vector = 5.*ones(1,p)

But this second method doesn't work... Why? Should I redraw the graph? How?

2) Now I can draw a line, I would like to draw the shortest path between 
2 points I compute with Dijkstra algorithm (or Floyd). Nevertheless, 
even with changing thickness option, the surface is often hiding my 
path. Any idea?
I attach all the functions I wrote in the file geodesiquefunctions.sci 
and a script to draw the shortest path between Paris and Tokyo 
shortestpath.sce.
If someone can take a look at it?

Subject: Can I draw a graph without giving "node_x" and "node_y" values? (show_graph)
 
Message-ID: <483DEEFF.3050003@free.fr>

Hello!

If I define a graph :
  g = make_graph('toto',0,3,[1,2,3],[2,3,1])
And I want to draw it :
  show_graph(g)

I get many errors begining with (I don't know how to copy/past from 
scilab interpretor output) :
  !-- error 60
  argument with incompatible dimensions
  ...

This error seems to come from the lack of "node_x" and "node_y" value... 
Nevertheless, I saw in the graph-list help page that these values are 
computed by default!
Could you help on this matter?

R?mi.

Hi,
I'd like using ilib_for_link function with C function build_in. So I'm
trying the help example bellow :
f1=['int ext1c(n, a, b, c)'
    'int *n;     double *a, *b, *c;'
    '{int k;'
    '  for (k = 0; k < *n; ++k) '
    '      c[k] = a[k] + b[k];'
    '  return(0);}'];

mputl(f1,'fun1.c')

//creating the shared library (a gateway, a Makefile and a loader are
//generated.

ilib_for_link('ext1c','fun1.o',[],"c")

// load the shared library

exec loader.sce

//using the new primitive
a=[1,2,3];b=[4,5,6];n=3;
c=call('ext1c',n,1,'i',a,2,'d',b,3,'d','out',[1,3],4,'d');
if norm(c-(a+b)) > %eps then pause,end

Loading the sce file, gives me this error :
in  execstr instruction    called by :

   compilation of fun1
   building shared library (be patient)

I believe i've tried this long time ago, and it works well.
Is there anybody knowing the answer to this pb ?

I also have another question about graph : how do I display the length

Exemple :
    Head = [1,2,3,4,1,2,3];
    Tail = [2,3,4,1,5,5,5];
    Longueur = [1,4,2,6,2,2,1];
    // Ar?te k d?finie par le triplet (Head(k),Tail(k),Longueur(k))
    graphe1 = make_graph('Figure 1',0,5,Tail,Head);
    graphe1.edge_length = Longueur;
    graphe1.node_x = [0,500,500,0,250];
    graphe1.node_y = [500,500,0,0,250];
    graphe1.edge_label = Longueur;
    graphe1.node_label = [1:5];
    show_graph(graphe1)

As you can see I try "edge_label" or "node_label" but it doesn't work... 
If someone can help me! I must finish my report for tomorow :p
