| *> \verbatim |
| *> |
| *> Test program for the COMPLEX Level 2 Blas. |
| *> |
| *> The program must be driven by a short data file. The first 18 records |
| *> of the file are read using list-directed input, the last 17 records |
| *> are read using the format ( A6, L2 ). An annotated example of a data |
| *> file can be obtained by deleting the first 3 characters from the |
| *> following 35 lines: |
| *> 'cblat2.out' NAME OF SUMMARY OUTPUT FILE |
| *> 6 UNIT NUMBER OF SUMMARY FILE |
| *> 'CBLA2T.SNAP' NAME OF SNAPSHOT OUTPUT FILE |
| *> -1 UNIT NUMBER OF SNAPSHOT FILE (NOT USED IF .LT. 0) |
| *> F LOGICAL FLAG, T TO REWIND SNAPSHOT FILE AFTER EACH RECORD. |
| *> F LOGICAL FLAG, T TO STOP ON FAILURES. |
| *> T LOGICAL FLAG, T TO TEST ERROR EXITS. |
| *> 16.0 THRESHOLD VALUE OF TEST RATIO |
| *> 6 NUMBER OF VALUES OF N |
| *> 0 1 2 3 5 9 VALUES OF N |
| *> 4 NUMBER OF VALUES OF K |
| *> 0 1 2 4 VALUES OF K |
| *> 4 NUMBER OF VALUES OF INCX AND INCY |
| *> 1 2 -1 -2 VALUES OF INCX AND INCY |
| *> 3 NUMBER OF VALUES OF ALPHA |
| *> (0.0,0.0) (1.0,0.0) (0.7,-0.9) VALUES OF ALPHA |
| *> 3 NUMBER OF VALUES OF BETA |
| *> (0.0,0.0) (1.0,0.0) (1.3,-1.1) VALUES OF BETA |
