Input | trans | Transposition option for A: | |
|
| ’N’ or ’n’ | Compute y ← αAx + βy |
|
| ’T’ or ’t’ | Compute y ← αATx + βy |
|
| ’C’ or ’c’ | Compute y ← αA*x + βy |
|
| where AT is the transpose of A and A* is the conjugate | |
|
| transpose. In the real subprograms, ’C’ and ’c’ have the | |
|
| same meaning as ’T’ and ’t’. | |
| m | Number of rows in matrix A, m ≥ 0. If m = 0, the | |
|
| subprograms do not reference ab, x, or y. | |
| n | Number of columns in matrix A, n ≥ 0. If n = 0, the | |
|
| subprograms do not reference ab, x, or y. | |
