We focus on the user's point of view, <br>that is, we have to minimize or maximize an objective function and must <br>find a solver suitable for the problem. The aim of this paper is to give <br>a simple but accurate view of what problems can be solved by Scilab and <br>what behavior can be expected for those solvers. For each solver, we <br>analyze the type of problems that it can solve as well as its advantages <br>and limitations. In order to compare the respective performances of the <br>algorithms, we use the CUTEr library, which is available in Scilab. <br>Numerical experiments are presented, which indicates that there is no
<br>cure-for-all solvers."<br><br>The flagship of Scilab in terms of general nonlinear optimization<br>is currently the optim function, which allows to perform<br>unconstrained and bound constrained optimization.<br>It is shortly presented at :<br><br><a href="http://wiki.scilab.org/The_optim_primitive" target="_blank">http://wiki.scilab.org/The_optim_primitive</a><br><br>and in the help of Scilab :<br><br><a href="http://www.scilab.org/product/man/optim.html" target="_blank">http://www.scilab.org/product/man/optim.html</a><br><br>You may get an overview of optimization features by<br>browing the help of Scilab :<br><br><a href="http://www.scilab.org/product/man/section_e75956809590b9cc1bb1d9aec86b31b8.html" target="_blank">http://www.scilab.org/product/man/section_e75956809590b9cc1bb1d9aec86b31b8.html</a><br><br>What kind of optimization do you plan to do ?<br><br>If you are interested in a general overview of Scilab, you may<br>consider the

For example, in order to connect your<br>C or C++ library to Scilab, you can use the Scilab API :<br><br><a href="http://www.scilab.org/product/man/section_204636e951f595409bc6782bb8e1d2d9.html" target="_blank">http://www.scilab.org/product/man/section_204636e951f595409bc6782bb8e1d2d9.html</a><br><br>Many examples are provided in the libraries which are already connected<br>inside Scilab.<br><br>Best regards,<br><br>Michaël Baudin<br><br><br>Prof. Dr. Reinaldo Golmia Dante a écrit :<br>> Hi all,<br>><br>> I would like to know how to use the optimization toolbox of SciLab.<br>><br>> This is my first time that I use Scilab and I would like to
