I am having a SparseMatrix A which has a certain sparsity pattern and a
How to perform the matrix multiplication
where diag(V) is a diagonal matrix with the vector V in the main diagonal.
is there any such function in dealii?
how to create the SparseMatrix diag(V) for a given vector V?
to my knowledge dealii on provided
A.mmult(C,B,V) for C= A*diag(V)*B or
A.mmult(C,B) for C= A*B
