The Generalized Nonsymmetric Eigenvalue Drivers

The driver routines for the generalized nonsymmetric eigenvalue problem are

xGGES

generalized Schur form driver

xGGESX

expert version of xGGES (includes condition estimation)

xGGEV

generalized eigenvalue/eigenvector driver

xGGEVX

expert version of xGGEV (includes condition estimation)

For these driver routines, some tests are done by generating random matrix pairs of a dimension and type chosen by users, and computing error bounds similar to those used for the nonsymmetric generalized eigenvalue computational routines. For some tests, one can use a file of precomputed matrix pairs and condition numbers.

The parameters that can be varied in the random matrix pair tests are:

175#175

the order N of the test matrix pair 174#174

175#175

the type of the test matrix pair 174#174
