Tests for the ScaLAPACK QR, RQ, LQ, QL, QP, and TZ routines

The QR test program generates random nonsymmetric test matrices with values in the interval [-1,1], calls the ScaLAPACK routines to factor the system, and computes a factorization residual error check to verify that each operation has performed correctly.

Specifically, each test matrix is subjected to the following tests:

The testing of the RQ, LQ, QL, and QP routines proceeds in a similar fashion. Simply replace all occurrences of QR in the previous discussion with RQ, LQ, QL, or QP respectively. For TZ, the factorization routine is called PxTZRZF.
