Hi there, After quite some pain, I finally managed to build a LAPACK + ATLAS rpm useful for numpy and scipy. Read the following if you use Fedora Core or OpenSuse and are tired to install unsuccessfully numpy, scipy, BLAS, LAPACK or ATLAS. Instructions are given there:

[Numpy-discussion] qr decomposition with column pivoting/qr decomposition with householder reflections

2007-06-24 Thread traveller3141
I'm in the process of trying to convert some Matlab code into Python. There's a statement of the form: [q,r,e] = qr(A) which performs a qr-decomposition of A, but then also returns a 'permutation' matrix. The purpose of this is to ensure that the values along r's diagonal are decreasing. I

IMO the Modular toolkit for Data Processing (MDP) has a fairly good and straightforward PCA implementation, among other good tools: mdp-toolkit.sourceforge.net/ I have no idea what apt-get is, though, so I don't know if this will be helpful or not! -Rob On 21/06/07, Alex Torquato S. Carneiro
