Testing the Generalized QR and RQ Factorization Routines

The test routine for the GQR and GRQ factorization routines has the following parameters which may be varied:

• the values of 487#487 of the test matrix 16#16
• the values of 520#520 of the test matrix 97#97
• the number of columns or rows 118#118 of the test matrices 16#16 and 97#97
• the number of matrix types to be tested

The test program thus consists of a doubly-nested loop, the outer one over ordered triples 521#521, and the inner one over matrix types. On each iteration of the innermost loop, matrices 16#16 and 97#97 are generated and used to test the GQR and GRQ routines.

Please note that the block size NB is not an input test parameter since the GQR and GRQ factorizations are implemented by calling the QR and RQ factorizations which have been tested for the parameter block size NB.
