ABOUT OPERATING PETScWrappers::MPI::SparseMatrix

[xs...@berkeley.edu]

Hi, I declared two same scale matrix A and B using PETScWrappers::MPI::SparseMatrix and assign values on these two matrixes. I want to do some operation on them to get another matrix C which equals h*A+B. How should I get the matrix C? Thank you very much.

This should work:

C = B;
C.add (h, A);
