Hi,

I have been using BVOrthogonalize in SLEPc with a symmetric positive definite matrix (say B) in my BVSetMatrix. I was wondering if I can create a shell matrix for B and use it to overload the MatMult operations. If yes, what MATOPs like MATOP_MULT, MATOP_MULT_TRANSPOSE, MATOP_GET_DIAGONAL should I provide?

Thanks, Bikash

Yes, it should be enough to provide MATOP_MULT. Jose
