Detailed Description

Eigenvalues and eigenvectors of a general square matrix (LAPACK ?geev).

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.
