Introduction to Scilab In this article, we present an introduction to discrete probabilities with Scilab. Numerical experiments are based on Scilab. The first section present discrete random variables and conditionnal probabilities. In the second section, we present combinations problems, tree diagrams and Bernouilli trials. In the third section, we present simulation of random processes with Scilab. http://forge.scilab.org/index.php/p/docintrotoscilab/ http://forge.scilab.org/index.php/p/docintrotoscilab/source/tree/HEAD/ http://forge.scilab.org/index.php/p/docintrodiscrprobas/downloads/ Introduction to Discrete Probabilities with Scilab In this article, we present an introduction to discrete probabilities with Scilab.

But, in many algorithms, some additional work is performed, which takes into account the fact that the computer does not process mathematical real values, but performs computations with their floating point representation. The goal of this article is to show that, in many situations, Scilab is not naive and use algorithms which have been specifically tailored for floating point computers. We analyze in this article the particular case of the quadratic equation, the complex division and the numerical derivatives. In each example, we show that the naive algorithm is not sufficiently accurate, while Scilab implementation is much more robust. http://forge.scilab.org/index.php/p/docscilabisnotnaive/ http://forge.scilab.org/index.php/p/docscilabisnotnaive/source/tree/HEAD/ http://forge.scilab.org/index.php/p/docscilabisnotnaive/downloads/ Nelder-Mead User's Manual In this document, we present the Nelder-Mead component provided in Scilab. The introduction gives a brief overview of the optimization features of the component and present an introductory example. Then we present some theory associated with the simplex, a geometric concept which is central in the Nelder-Mead algorithm. We present several method to compute an initial simplex. Then we present Spendley's et al. fixed shape unconstrained optimization algorithm. Several numerical experiments are provided, which shows how this algorithm performs on well-scaled and badly scaled quadratics. In the final section, we present the Nelder-Mead variable shape unconstrained optimization algorithm. Several numerical experiments are presented, where some of these are counter examples, that is cases where the algorithms fails to converge on a stationnary point. In the appendix of this document, the interested reader will find a bibliography of simplex-based algorithms, along with an analysis of the various implementations which are available in several programming languages. http://forge.scilab.org/index.php/p/docneldermead/ http://forge.scilab.org/index.php/p/docneldermead/source/tree/HEAD/ http://forge.scilab.org/index.php/p/docneldermead/downloads/ Artem Glebov a ?crit : > Hello, > > I would like to translate the document "Introduction to Scilab" (by Micha?l > Baudin) into Russian. > > Please tell me: > 1) if anybody is doing this job already (translating tutorials from English > to Russian)? > 2) where I can find the template (LaTeX, I guess) for this document and > picture files? > > Thank you. > Artem Glebov > > -- Micha?l Baudin Ing?nieur de d?veloppement michael.baudin at scilab.org ------------------------- Consortium Scilab - Digiteo Domaine de Voluceau - Rocquencourt B.P. 105 - 78153 Le Chesnay Cedex Tel. : 01 39 63 56 87 - Fax : 01 39 63 55 94 From communication at scilab.org Wed Apr 21 14:05:56 2010 From: communication at scilab.org (Scilab Communication) Date: Wed, 21 Apr 2010 14:05:56 +0200 Subject: Release of Scilab 5.2.2 Message-ID: <4BCEEA24.4090800@scilab.org> Dear all, The Scilab R&D Team is pleased to announce the release of Scilab 5.2.2.

We are currently using Gerrit [2] which is a tool developed by Google for their internal needs. They released it as a free software project [3] less than a year ago. We used to do this task in the past but it was informal and painful (watching the git/svn log, watching the modifications, testing and sending emails to the author) and we hope improving the overall quality of the code included into Scilab and match on every commit the requirements [4]. We also wrote some extended coding styles for C [5] and Scilab [6] in the Scilab code. Finally, we will probably ask students of the Google Summer of Code 2010 to go through the Code Review system for their codes (into Scilab or for external modules).

Good question. You probably know but it is easy to retrieve scilab-bin with sciargs. About the Scilab script, in most of the case, you should be able to find it with: SCI+"../../bin/scilab" I agree this is not what you expect but this will work with both official binaries and distribution packages (grosso modo, as long as the user does not force a weird data directory) Sylvestre -- ------------------------- Sylvestre Ledru ------------------------- The Scilab Consortium Digiteo Domaine de Voluceau Rocquencourt - B.P. 105 78153 Le Chesnay Cedex France From stephane.mottelet at utc.fr Mon Apr 26 17:43:50 2010 From: stephane.mottelet at utc.fr (=?UTF-8?B?U3TDqXBoYW5lIE1vdHRlbGV0?=) Date: Mon, 26 Apr 2010 17:43:50 +0200 Subject: [Scilab-Dev] a kind of regression In-Reply-To: <1272296355.29581.24.camel@zlarin> References: <1272283059.1523.79884.camel@korcula.inria.fr> <4BD5AC95.8090304@utc.fr> <1272296355.29581.24.camel@zlarin> Message-ID: <4BD5B4B6.8020802@utc.fr> Le 26/04/2010 17:39, Sylvestre Ledru a ?crit : > Le lundi 26 avril 2010 ? 17:09 +0200, St?phane Mottelet a ?crit : > >> Hi all, >> >> Since the 5.0 version is it no more possible to know the location >> of Scilab main script by using the SCI variable.

If you find somewhere it is not the case, it is a bug. Actually, I would you this solution. I though that sciargs would give you back only the path a relative but in fact, it is absolute. For example: $ /usr/share/../bin/scilab -nwni -e "disp(sciargs())" -nb !/usr/bin/scilab-bin -nwni -e disp(sciargs()) -nb ! So, you should go with this solution!

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.). 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); --- with t0=0.17, pas_temps=0.001 et tf=t0+pas_temps 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?less than that: the intermediate?times used by the "rkf" method are 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. So I defined myself a function rkf. After testing it, it returned the same results as given by integrating only x and y using the function ode. An explanation of that mystery? Where can I find the code of the Scilab function ode? Thank you in advance. -------------- next part -------------- An HTML attachment was scrubbed...

The difference in execution time when the system is lower or upper triangular is probably due to the fact that with lower triangular the lu factorization cost almost nothing....

Date: Fri, 30 Apr 2010 19:37:36 +0100 Subject: DAQ System Project Message-ID: Dear Sir/Madam, I am a student from the University of Leicester, UK who is studying in the third year of a four year course in engineering. In the fourth year of the course all students have to do a group project. A couple of students and I have planned on doing a project which is to upgrade a simple computer driven control system using Scilab and Xcos (or as it used to be called, Scicos). In addition to this, we are also planning on creating a simple DAQ system to be used with Scilab and Xcos. We thought you might be interested in knowing this and wanted to know if there is anything special you would like us to do while we complete this project which would at the same time benefit us? Especially with regards to the DAQ system. I will be willing to answer any questions in relation to this topic. Regards, Jerome Clayton
