Test Matrices for the Constrained Linear Least Squares Driver

Eight different test matrix combinations are used for the LSE test path. All are generated with a predetermined condition number. The following test matrices are used:

NTYPES Matrix A Matrix B 522#522 523#523 524#524 525#525
1 Diagonal Upper triangular 10 1000 100 10
2 Upper triangular Upper triangular 10 1000 100 10
3 Lower triangular Upper triangular 10 1000 100 10
4 Random dense Random dense 10 1000 100 10
5 Random dense Random dense 10 1000 100 10
6 Random dense Random dense 10 1000 100 10
7 Random dense Random dense 10 1000 100 10
8 Random dense Random dense 10 1000 100 10

Please note that the current version of the LSE driver only addresses well-conditioned problems (like xGELS does). Therefore, we do not test the code with ill-conditioned matrices.
