[Libmesh-users] SparseMatrix Determinant

[Barna B. <bar...@gm...>]

Hello,

is there a way to compute a SparseMatrix’s determinant? I would like to solve a linear system but my final residual always equals exactly 0 after just one iteration (where the solve terminates). Hence, I would like to check the matrix for singularity.
Thank you.

Sincerely,

Barna
