When I set the environment variable in a command prompt, it doesn't work in the short cut, but when I set it in Scilab (n is an integer) setenv("timer_time", string(n)); and use %timer_time% in the short cut, it works! Can anybody explain why?

The plot is apparently not correct, because It shows that the Impulse method is the better one, except that the continuous curve has been shifted (see and compare graph 1 and 2) I had to redraw all the graphs using the repfreq, dbphi, and plot2d instructions to get correct results, which show that the Bilinear method is the best one (graph 4) So I think there is a bug in the Bode plot, or a method error (SIMO // SISO ?)

When I execute my script again, scilab displays the following (translated from German): exec('c:\...path.....\test.sci', -1) Warning: redefining function: test. Use funcprot(0) to suppress this warning. The warning message makes sence because funcprot = 1 "= warning". But the execution of my script seems to be interrupted by this warning.

I'm not aware of any way to prevent this. What you might do is to draw your graphs in the same window, using the subplot command (which allows to put several graphs in separate subwindows), and postpone drawing until your script's execution is over, with the drawlater/drawnow commands. For example: scf(0); drawlater; // postpones drawing // script execution for graph #1 subplot(2,2,1); plot2d(); // first graph // script execution for graph #2 subplot(2,2,2); plot2d(); // 2nd graph // etc. drawnow; // executes the previous plot commands This will grab the focus only once, when the scf(0) command is performed, and allow your script to run without repeatedly grabbing the focus due to window creation. -- ------------------------- Manuel Juliachs Ing?nieur de d?veloppement ------------------------- Consortium Scilab Digiteo Domaine de Voluceau Rocquencourt - B.P. 105 78153 Le Chesnay Cedex France T?l. : +33.1.39.63.52.71 From anders at simbalsyd.se Wed Apr 7 10:54:37 2010 From: anders at simbalsyd.se (Anders Sneckenborg) Date: Wed, 7 Apr 2010 10:54:37 +0200 Subject: plot in batch Message-ID: <14C7CA18C15381499784EEA3E73E5BF402215694A1@PRISMA.simbalsyd.local> Hi I have a script which takes long time to run and when running it creates several graphs.

It is possible to display a real matrix as an image with Matplot or Matplot1 as said before. Here is an example clf Ncolors=70; // Number of colors whished M=grand(200,200,"uin",0,Ncolors); // Creating data. Replace by your own real matrix M RGB=graycolormap(Ncolors+1); // You can choose another colormap. Here is the grey one.

Then use functions ReadImage() and ShowColorImage(). If your OS is Linux-like, SIVP that is not (yet?) an ATOMS module but an external toolbox, will be useful (imread() + imshow()).

I suggest that you download the file IPD-5-0-Windows.zip from atoms.scilab.org/toolboxes/IPD/5.0 and extract it to the directory C:\Program Files\scilab-5.2.1\contrib\ Then there should be the directory C:\Program Files\scilab-5.2.1\contrib\IPD-5.0\ and you can load the toolbox after re-launching Scilab. You can execute the command atomsInstall(['IPD' '5.0']) on the Scilab command line instead. This still downloads and extracts IPD-5-0-Windows.zip, but the directory structure might be C:\Program Files\scilab-5.2.1\contrib\IPD\5.0\ then. If this happens, move the directory C:\Program Files\scilab-5.2.1\contrib\IPD\5.0\ to C:\Program Files\scilab-5.2.1\contrib\ and rename it to IPD-5.0. Then there will be the directory C:\Program Files\scilab-5.2.1\contrib\IPD-5.0\ You can choose another name for the directory. However, the online help examples assume that there is the directory contrib\IPD-5.0\demos\ Both ATOMS GUI and atomsInstall download and extract the ZIP file, but do not create the directory structure necessary for loading the toolbox. I do not know why. Best regards Harald ----- Urspr?ngliche Mail ---- Von: Luke MacAleese An: users at lists.scilab.org Gesendet: Mittwoch, den 7.

Well, you can also have the Scilab engine available without the Java VM. See Call_Scilab: http://www.scilab.org/product/man/call_scilab.html You can also give a try to Scilab2C for such things: http://atoms.scilab.org/toolboxes/scilab2c/ but obviously, just a subset of Scilab is available.

However, if I make x0=[1] or x0=[2], I get realizations starting from any of the states (sometimes state 1 and sometimes state 2) and that does not make much sense to me, because then, what are the limiting-state probabilities that the function is using to choose the initial state? According to what is explained in the grand() help page, if I make, for example, x0=[1], shouldn't the sequence 'always' start in state 1?

Actually, for a file, being opened in the editor does not mean being opened in the Scilab session (console), even if the editor has been launched from the session. I agree that this does not look obvious. To check that : open a file in xpad (embedded editor); then in the console: dispfiles() => The file opened in xpad is not listed. Moreover : The file is opened while it is beING executed. This is why in practical, get_absolute_file_path() can be used either in .sce scripts (list of instructions) ; or whether the file has been opened with mopen() of file(...

For your application, the better way is to gather your functions in a library. See genlib(). Then, it would be possible to use whereis() and libraryinfo() to recover the path to files.

When I run the examples in the XML it works pwrfect. I can see all the examples, specially the Lapace Equation and the Earth-Moon orbit.. But as I ran this simple test: clc() n=[1:20] z=exp(%i*2*%pi.*n./10); phz=atan(imag(z),real(z)); plot(n,phz) I can not see any plot in the screen. But without the module running, I can plot.. I noticed that when I finished installing the module, seems like the the program does not include a reg key and libplot is not working correctly.. just speculating... Also, I can not un-install the module. I have to delete the entire directory (brute force)..

XMLlab plots graphics in pixmap mode, so if you plot in a simulations's window (after the simulation has stopped) then the window is still in pixmap mode. If you don't especially need to plot over the simulation plots, then close the window and plot in a "fresh" one, and otherwise set the pixmap mode to off with set(gcf(),'pixmap','off'). > > I noticed that when I finished installing the module, seems like the > the program does not include a reg key and libplot is not working > correctly.. just speculating... > I assume you are using windows, but what is libplot ? > Also, I can not un-install the module.

After the Sylvestre's remark, please note that, like it is presented on the curl main webpage, and like Scilab, / Curl is free and open software that compiles and runs under a wide variety of operating systems. Curl exists thanks to efforts from many contributors . / Therefore, you can freely instal it on your machine, and use it through the unix() scilab's command. So, back-compatibility cannot be a concern. Cheers Samuel -------------- next part -------------- An HTML attachment was scrubbed...

In order to properly analyse the result of these fits, I would like to get an estimate of the standard error on each parameter (or an interval of confidence at 95%). So far, the only way I found to retrieve the interval of confidence is to do bootstrapping but it requires repeating the fitting procedure ~ 100 times. I am looking for a less computer-intensive solution. As far as I understood, leastsq is using minpack to implement the Levenberg-Marquardt algorithm. Is there a way to get access to the covariance matrix with leastsq, optim or any other scilab routine? This would be way faster and easier than bootstrapping.

I am trying to develop a model/GUI in Scicos that allows a user to: 1. Acquire images from a target hardware 2. Apply image processing algorithm to acquired image 3. Plot relevant parameters 4. Change parameters of the hardware At the moment, I am concentrating on step 1. My problem right now is: 1. After reading the BMP image using a C routine, I convert the image array to a Scilab matrix. How can I use this Scilab matrix as an input to the CMATVIEW block to view the image? Other relevant information: I will only be dealing with gray-scale images. The colormap information of BMP file is not important. The image array I mentioned above, only contains pixel information. The Scilab matrix will be a two-dimensional structure of pixels. I set the CMATVIEW parameters to: { graycolormap(256), 0, 255} In order to share data between Scilab and Scicos, I added the following lines in the C routine (The C routine is executed when the function is called with flag 4): // CreateVarFromPtr(1, "i", &xout, &yout, &out); // (*blk).outptr[0]=istk(1); "xout" is the height of the BMP file in pixels "yout" is the width of the BMP file in pixels "out" is the array of pixel data But, the CMATVIEW block does not display image. There are no error messages in either Scilab/Scicos during simulation. When I stop simulation, the display window of CMATVIEW freezes and I am unable to close it after that. I am using a Generic block for this C routine. The output port of Generic Block is connected to the input port of CMATVIEW. I modified the output port size of Generic Block to [80, 80] which are the row and column widths of the image. I hope this description is clear. Please feel free to contact me if you need clarification or additional information. Thank you. -------------- next part -------------- An HTML attachment was scrubbed...

Going over that Scilab just crashes. With previous Scilab versions I only could get 256MB. Believe it or not, regularly I needed a bit more than that. However when using this maximum I found the help function does not work very well or makes Scilab crash. This might also affect or Scilab functions (probably the editor too etc). So perhaps it is good to leave some headroom. To avoid setting the stacksize manually every time you can make a text-file called .scilab with the line stacksize(512*1024*1024) and put the file in your /.Scilab/.scilab-5.2.2 folder in usually your home directory.

On the 5.2.x branch, you can reuse your current scicos implementation as the core is the same. As in Scicoslab, you just need to load your block interface function into the interpreter (myblock.c), provide macros block descriptor (MYBLOCK_f.sci) and a reference instance in a palette (MYPALETTE.cosf). Then just open your palette on xcos as a normal diagram or use palettes/Open as palette button. For the 5.3.x branch (current master), we will probably provide an API to add/remove/customize h5 blocks from Scilab. Thus user will be able to implement Xcos palettes as Scilab toolboxes.

Message-ID: <4BD6CD67.9060803@developpement-durable.gouv.fr> Dear scilab users, I am currently working on a scilab project for signal processing. It is actually a set of different functions processing simulated MLS signals. Each functions are called sequencially, produce a 2d-plot of the signal and the user can click on the plot to add a Black-Harris windows and finally some characteristics are computed. I would like to unify and generate all computations through a friendly GUI. I have searched the web for more information and I have found we can call scilab from different low-level languages (C, fortran, java...). My question is to know wether it is possible to call some Java from scilab, such a graphical components, in order for me to develop a java-based GUI ? Thank you for any answers.

I have a problem using ode "rkf". I?defined a function like that : --- function Xdot = F(t,X) ? [v1,v2,v3] = fonc(t,X(1),X(2)); ? xdot = v1; ? ydot = v2; ? Adot = v3; ? Xdot = [xdot; ydot; Adot]; endfunction --- then I used : --- Sol = ode("rkf",X0,t0,t0:pas_temps:tf,F); --- In this case, xdot and ydot don't depend on A=X(3), I obtain however a different result for x=X(1) and y=X(2) compared with the result obtained by integrating only x and y (same initial condition, etc.). I?noticed that it depended on how I define Adot. For example, doing this : --- function Xdot = F(t,X) ??printf("t=%f \n",t); ? ? [v1,v2,v3] = fonc(t,X(1),X(2)); ? xdot = v1; ? ydot = v2; ? Adot = 1; ? Xdot = [xdot; ydot; Adot]; endfunction ? Sol = ode("rkf",X0,t0,t0:pas_temps:tf,F); --- with t0=0.17, pas_temps=0.001 et tf=t0+pas_temps leads to : --- t=0.170000 t=0.170250 t=0.170375 t=0.170923 t=0.171000 t=0.170500 t=0.171000 --- I verified that these times correspond to the intermediate?times used by the "rkf" method : t0, t0+1/4*pas_temps, t0+3/8*pas_temps, t0+12/13*pas_temps, t0+pas_temps, t0+1/2*pas_temps, as said here http://math.fullerton.edu/mathews/n2003/RungeKuttaFehlbergMod.html. Now if I use for example : --- function Xdot = F(t,X) ??printf("t=%f \n",t); ? ??[v1,v2,v3] = fonc(t,X(1),X(2)); ? xdot = v1; ? ydot = v2; ? Adot = v3; ? Xdot = [xdot; ydot; Adot]; endfunction ? Sol = ode("rkf",X0,t0,t0:pas_temps:tf,F); --- ? then Scilab returns that : --- t=0.170000 t=0.170250 t=0.170375 t=0.170923 t=0.171000 t=0.170500 t=0.170218 t=0.170326 t=0.170803 t=0.170870 t=0.170435 t=0.170870 t=0.170903 t=0.170919 t=0.170990 t=0.171000 t=0.170935 t=0.171000 --- and as a consequence that changes the results for x and y (they are supposed not to change because they don't depend on A). I checked?the definition of v3 and don't see errors. For me, the number of intermediate times is supposed to be the same, am I right ? An explanation of that mystery ? Thank you in advance. -------------- next part -------------- An HTML attachment was scrubbed...

Thus the `loadScicosLibs` macros doesn't load libsciscicos.so. For your purpose simply load it with a raw scicos call. For example use : --> scicos_debug(); before linking your library. For the record, I posted a bug [http://bugzilla.scilab.org/show_bug.cgi?id=7005] for discussion about loading this library on the `loadScicosLibs` macros.

I do not understand your scientific problem, I will simply give you some practical advices. It is likely that you are using an integer index n which is either too large or too small with respect to the size of your array vx. The line vx=zeros(1,1);for n=1:3000 vx(:,n+1)=vx(n)+(ax(:,n+1)-ax(:,n))*.(0.01/2);end; which generates the error message is too long: you cannot trace back to the problem. What happens if you run this ? vx=zeros(1,1); for n=1:3000 vx(:,n+1)=vx(n)+(ax(:,n+1)-ax(:,n))*.(0.01/2); end; If you do not understand what is the problem, you can insert a pause in the loop and directly play with your algorithm with resume (which will make you go on to the next loop) and abort (which will make you go out of the loop) : vx=zeros(1,1); for n=1:3000 pause vx(:,n+1)=vx(n)+(ax(:,n+1)-ax(:,n))*.(0.01/2); end; Hope this helps.

The nearest one is polarplot(), if you need to get the polar frame in the background. Else, result of plot2d() may be easier to handle and customize. Anyway, you will have to add some lines of code to customize the plot afterwards.

In fact the documentation was the one of scilab-4.1.2. I just tried with the link you gave (scilab-5.2.2), and it's ok. It was just because I didn't download the sources (shame on me!), I did it for scilab-4.1.2. and it's?also ok.?So no problem. Thanks again. ________________________________ De : calixte ? : users at lists.scilab.org Envoy? le : Jeu 29 avril 2010, 20 h 43 min 17 s Objet?: Re: [scilab-Users] Access to ode code Hello, i) You should report the bug at bugzilla.scilab.org ii) I found these files in the directory scilab/modules/differential_equations/src/fortran in the source distribution (http://www.scilab.org/communities/developer_zone/scilab_versions/stable) Calixte Le jeudi 29 avril 2010 ? 11:14 -0700, Bouchra Bensiali a ?crit : > Hi, >? > I want to have access to the Scilab code of the function ode.

For example, if I define a function F: -- function Xdot=F(t,X) ? //printf("t=%f \n",t) ? ? Xdot = ... ; ? endfunction; -- and make a first integration: -- pas_temps = 0.001; t0 = 170*pas_temps; tf = 180*pas_temps; X0 = ... ; Trajectoire1 = ode("rkf",X0,t0,t0:pas_temps:tf,F); -- and a second integration beginning with the result obtained at time t=0.178 (for example): -- t0 = 178*pas_temps; tf = 180*pas_temps; X0 = Trajectoire1(:,9); Trajectoire2 = ode("rkf",X0,t0,t0:pas_temps:tf,F); -- then is Trajectoire2 supposed to be the same as Trajectoire1(:,9:11)? Because I have an example that gives different results and found (by using printf("t=%f \n",t)) that the number of intermediate times changed from one integration to another. Thank you in advance for your help. I'm really stuck. -------------- next part -------------- An HTML attachment was scrubbed... URL:
