Detailed Description

Holds internal status data about the owning Amesos2 solver.

Provides convenient access to status data for both solvers and outside users.

Member Function Documentation

size_t Amesos2::Status::getNnzLU ( ) const

inline

Get the number of non-zero entries in the $L$ and $U$ factors.

Returns 0 if numeric factorization has not yet been performed, or if the solver does not support getting statistics about the factors.
