| 2 | * |
| 3 | * Test program for the DOUBLE PRECISION Level 2 Blas. |
| 4 | * |
| 5 | * The program must be driven by a short data file. The first 18 records |
| 6 | * of the file are read using list-directed input, the last 16 records |
| 7 | * are read using the format ( A6, L2 ). An annotated example of a data |
| 8 | * file can be obtained by deleting the first 3 characters from the |
| 9 | * following 34 lines: |
| 10 | * 'DBLAT2.SUMM' NAME OF SUMMARY OUTPUT FILE |
| 11 | * 6 UNIT NUMBER OF SUMMARY FILE |
| 12 | * 'DBLAT2.SNAP' NAME OF SNAPSHOT OUTPUT FILE |
| 13 | * -1 UNIT NUMBER OF SNAPSHOT FILE (NOT USED IF .LT. 0) |
| 14 | * F LOGICAL FLAG, T TO REWIND SNAPSHOT FILE AFTER EACH RECORD. |
| 15 | * F LOGICAL FLAG, T TO STOP ON FAILURES. |
| 16 | * T LOGICAL FLAG, T TO TEST ERROR EXITS. |
| 17 | * 16.0 THRESHOLD VALUE OF TEST RATIO |
| 18 | * 6 NUMBER OF VALUES OF N |
| 19 | * 0 1 2 3 5 9 VALUES OF N |
| 20 | * 4 NUMBER OF VALUES OF K |
| 21 | * 0 1 2 4 VALUES OF K |
