Works for me!
Thanks for tackling this issue. I was worried that lobpcg wouldn't be
ready for the next release.
Robert, could we switch the order of the A and BlockVectorX
parameters? Having A first matches the convention used by other
iterative solvers in SciPy.
Also, we should provide a short description of what the method
computes in terms of A, B, lambda, etc. A small example would be nice
too (since the interface is a little different than, e.g. ARPACK).
