Hi! Barry> Certainly pointwise addition is the same as adding two operators Barry> together (PETSc has this with MatAXPY), but what about, for example, Barry> pointwise multiply?
Pointwise multiply is the Hadamard product of two matrices matrix. You have something like MatGetRowMax which strictly speaking is not a matrix operation in the linear algebra sense. So why not something like MatGetRowNorm? vishy
