Adding two matrix with different sparsity pattern

8 months ago by

I was wondering if there is a way of adding 2 different matrix with different sparsity pattern. More specifically, I have a matrix "assembled" in fenics and I want to add another self-constructed matrix (with the same dimension but different sparsity pattern to it). Is there a way to do it?

If you want A1+A2, I think you can try to use axpy and set the last argument to False.

A1.axpy(1.0, A2, False)
