Testing the Eigensystem Routines

a)
Go to LAPACK/TESTING/EIG and type make followed by the data types desired. The executable files are called xeigtsts, xeigtstc, xeigtstd, and xeigtstz and are created in LAPACK/TESTING.

b)
Go to LAPACK/TESTING and run the tests for each data type. The tests for the eigensystem routines use eighteen separate input files for testing the nonsymmetric eigenvalue problem, the symmetric eigenvalue problem, the banded symmetric eigenvalue problem, the generalized symmetric eigenvalue problem, the generalized nonsymmetric eigenvalue problem, the singular value decomposition, the banded singular value decomposition, the generalized singular value decomposition, the generalized QR and RQ factorizations, the generalized linear regression model, and the constrained linear least squares problem. The tests for the REAL version are as follows: The tests using xeigtstc, xeigtstd, and xeigtstz also use the input files nep.in, sep.in, svd.in, glm.in, gqr.in, gsv.in, and lse.in, but the leading `s' in the other input file names must be changed to `c', `d', or `z'.

If you encountered failures in this phase of the testing process, please refer to Section 6.8.
