Could you clarify this please? Let's say that I want to make a call to the LAPACK routine sspevd, and pass it a matrix, and get the result. How do I accomplish this? Thanks, Daran -- http://mail.python.org/mailman/listinfo/python-list

Hi John, When I built Numeric with ATLAS and LAPACK, the eigenvalue calculation took the same amount of time. Per your suggestion, I will capture the output of the build and post it to the Numpy discussion group. Thanks, Daran -- http://mail.python.org/mailman/listinfo/python-list

Thanks John. Those are the steps I followed, and to no avail. Interestingly, I downloaded and installed SciPy, and ran the same eigenvector problem. SciPy greatly speeds up the calculation...was 1.5 hours using Numeric, now only 15 min with SciPy. Unfortunately, SciPy only solves ordinary and gen

Installing Numeric with ATLAS and LAPACK

Hello, Could someone please provide instructions for install Numeric with ATLAS and LAPACK? I've actually done this correctly, I think. But I don't see any difference in the speed. I'm calculating eigenvalues for a 3600 X 3600 covariance matrix. Calculating the eigenvalues for this matrix requi
