Detailed Description

Extract eigensystem of asymmetric matrix M, using the EISPACK routine.

vnl_eigensystem is a full-bore real eigensystem. If your matrix is symmetric, it is much better to use

Extract eigensystem of non-symmetric matrix M, using the EISPACK routine rg.

Should probably switch to using LAPACK's dgeev to avoid transposing.
