Testing the Generalized Singular Value Decomposition Driver

The driver routine for the generalized singular value decomposition is

xGGSVD

computes the generalized singular value decomposition of matrices 16#16 and 97#97

The test routine for this driver has the following parameters which may be varied:

• the number of rows 487#487 of the test matrix 16#16
• the number of rows 520#520 of the test matrix 97#97
• the number of columns 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 GSVD routines.

Please note that the block size 119#119 is not an input parameter since at the present time no blocked version of GSVD exists.
