Detailed Description

Template interface to LAPACK (in its original F77 implementation)

Typically, generic templates will throw an appropriate exception, while templates specialized for float, double, etc. will perform the requested calculations via corresponding LAPACK routines.

This code is rather low-level. It may be more convenient to use the API provided by the Matrix class which will eventually call appropriate LAPACK interface functions from here.
