I am wondering for the matrix type SumMatrix, do we have a way to take inversion?
For example, I have
hat = A.mat - B.mat@M.mat.Inverse(fesQ.FreeDofs(),inverse=“umfpack”)@B.mat.T
Do we have
“hat.Inverse”?
Thank you!

Which method do you want to use for the inverse? I see two black-box possibilities:
CGSolver
)hat.ToDense()
), and use a dense inverseDon’t know if you like any of them. H-matrices could be nice option, but not available, currently.
Thanks for your response. I prefer to convert the sum to a dense matrix and use a dense inverse. I will try and update later.
