Generalized Eigenvalue problem

Dear NumPythoneers, I have to solve the generalized Eigenvalue problem A u = lambda B u There are lapack procedures http://netlib2.cs.utk.edu/lapack/lug/node37.html. These procedures are not present in the lite versions included in the NumPy distribution. Did somebody already treat such problems?? Within Numpy or outside Numpy. Do I have to install the full blown version of Lapack?? Wim Vanroose

Yes, but it's not a big deal. If you then want a nicer high-level interface, look at the module LinearAlgebra for guidance; input parameters to LAPACK are treated rather consistently, so you shouldn't have to invent anything reallly new. -- ------------------------------------------------------------------------------- Konrad Hinsen | E-Mail: hinsen@cnrs-orleans.fr Centre de Biophysique Moleculaire (CNRS) | Tel.: +33-2.38.25.55.69 Rue Charles Sadron | Fax: +33-2.38.63.15.17 45071 Orleans Cedex 2 | Deutsch/Esperanto/English/ France | Nederlands/Francais -------------------------------------------------------------------------------
