Detailed Description

Solves a square linear system by LU factorization (LAPACK ?gesv).

Thin wrapper over the Fortran routine: BELFEM containers are passed straight through after their leading dimensions are worked out. Arguments are not copied – see each parameter for what is overwritten in place.
