Detailed Description

Extract eigensystem of unsymmetric 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 vnl_symmetric_eigensystem.

Constructor & Destructor Documentation

vnl_real_eigensystem::vnl_real_eigensystem

(

vnl_matrix< double > const &

M

)

Extract eigensystem of unsymmetric matrix M, using the EISPACK routine rg.

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