Scilab Enterprises is glad to announce the release of Scilab 5.5.1. Scilab 5.5.1 is a minor release to solve in particular three serious issues: ? * Scilab could not be used on Linux platforms using old GLIBC versions (CentOS, RedHat, etc.), ? * ATOMS modules update failed in some configurations, * The Japanese and Russian help pages were not available on Linux versions. Scilab 5.5.1 is available for download on http://www.scilab.org Best Regards -- SE Communication Department, Scilab Enterprises 143bis rue Yves Le Coz - 78000 Versailles (France) http://www.scilab-enterprises.com - http://www.scilab.org -------------- next part -------------- An HTML attachment was scrubbed...

Now, these additional libraries have been updated and Scilab 5.5.1 installation under 32 and 64-bit Windows is done properly. *Users should delete the additional files downloaded during the first installation to be able to reinstall and take advantage of all Scilab 5.5.1 performance.* Note that it is not necessary to download again Scilab installer (scilab-5.5.1.exe and scilab-5.5.1_x64.exe). Process to follow: Remove the additional files downloaded at the first installation of Scilab 5.5.1 (some files may not be present on your computer depending on the installation type you followed): -Under 32-bit Windows: oblas-lapack-mkl-5.5.1-win32.zip ocommons-mkl-5.5.1-win32.zip , offtw-mkl-5.5.1-win32.zip , -Under 64-bit Windows: oblas-lapack-mkl-5.5.1-win64.zip , ocommons-mkl-5.5.1-win64.zip , offtw-mkl-5.5.1-win64.zip -Restart the installation of Scilab 5.5.1 by double clicking: oUnder 32-bit Windows, on scilab-5.5.1.exe oUnder 64-bit Windows, on scilab-5.5.1_x64.exe Please accept our apologies for the inconvenience.

To take a look at this big piece of Scilab code, edit do_compile_superblock42 . To link to a program, you can compile the generated code and the simulation function from Scilab source code (SCI/modules/scicos_blocks/src/c). To easily target a specific hardware you have perform the integration of the code to the hardware manually : * to map inputs / outputs to generated ones, see the generated code. * to setup a task on your embedded OS or code a startup loop * calling the generated integrator each N time step, corresponding to the diagram * update I/O For people working on the subject and as far as I know : * X2C use a different approach and only map a set of block from their own block library. http://www.mechatronic-simulation.org/ * Geneauto map a set of blocks based on the Scicos library and use a their own scheduler and code generator http://forge.scilab.org/index.php/p/geneauto-p * Equalis forked Geneauto and add specific Michochip's blocks to ease I/O mapping * Evidence has developed E4Coder based on the do_compile_superblock42 approach but does not support Xcos. * And of course, at Scilab Enterprises, we are working on the subject and will be happy to apply patches to do_compile_superblock42.

Thanks, As the problem is underdetermined the equation as an infinity of solutions as follow. I will describe the process with the equivalent equation B'*R'=A that can be written suing standard notations as X*A=B, where A is a column vector X the row vector of the unknowns A can be factored as the product Q*R where Q is an othonormal square matrix and R a column vector whose all elements but the first one are zeros So the equation X*A=B can be rewritten (X*Q)*R=B or Y*R=B, all Y of the form [B/R(1),y2,....yn] are solutions, and consequently all X= [B/R(1),y2,....yn]*Q' are solutions of the initial equation Example -->A=(1:5)';B=4.5; -->[Q,R]=qr(A);R -->Y=[B/R(1),rand(1,4)]; -->Y*R-B ans = 0. -->X=Y*Q' -->X*A-B ans = - 8.882D-16 The particular solution computed by B/A serach for y2...yn that maximize the number of 0 in the solution X.
