Hi,
I think you can also use scipy.sparse.linalg.eigen.arpack in addition to
scipy.sparse.linalg.eigen.lobpcg
Also, from my experience with this routines I can tell you that they
don't like to be asked a small number of eigenvalues.
Contrary to common sense I have found these routines to prefer
Hi,
I need to solve symmetric generalized eigenvalue problems with large,
sparse stiffness
and mass matrices, say 'A' and 'B'. The problem is of the form Av =
lambdaBV. I have been using lobpcg (scipy.sparse.linalg.lobpcg), in
Scipy 0.7.2, although this has been giving me incorrect values that
