Is MATLAB optimized for the Pentium IV?

MATLAB 6.5 (Release 13) does indeed contain BLAS libraries optimized for the Pentium IV, though more recent versions of ATLAS (the BLAS library included with MATLAB) will further increase performance. If you are using Release 12 or want to try to improve performance, you can compile your own. Kevin Sheppard has been kind enough to prepare a web page with instructions for compiling your own ATLAS libraries on windows. He also provides ready-to-download DLLs for most common x86 processors. Find it at http://weber.ucsd.edu/~ksheppar/matlab/MatlabAtlas.htm. If you are running Linux, search the newsgroup archives for references to ATLAS. It is straightforward to compile your own customized version.
