Has anyone tried my patch to LinearAlgebra.py and lapack_litemodule.c? I've found major speedups (by a factor of 3-5) in all operations involving an svd or a eigenanalysis of a symmetric matrix. Paul's initial comment was that since it was not self-contained (it required linking external blas and lapack libs) he could not consider putting it in. I have rectified that now by including new versions of f2c_lite.c, blas_lite.c and d(z)lapack_lite.c that support the newer, faster lapack routines. I would appreciate any reports on how it works (or doesn't) on other platforms - I've tried it in on MacOS X and Solaris. Grab it from the 'Patches' section of the sourceforge project page. -Jeff -- Jeffrey S.
