Description

The EigenDecompositionImpl class contains methods to calculate the eigenvalues/eigenvectors of real symmetric matrices. However, for real asymmetric matrices there are currently no methods available to do this.
It would be nice if commons-math could be enhanced to provide this extra functionality.

Please note that the JAMA package contains a possible implementation in its EigenvalueDecomposition class.
