[petsc-users] Shell matrix in BVOrthogonalize

[Bikash Kanungo]

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
