1 PROGRAM cblat3
2*
3* Test program for the COMPLEX Level 3 Blas.
4*
5* The program must be driven by a short data file. The first 13 records
6* of the file are read using list-directed input, the last 9 records
7* are read using the format ( A12, L2 ). An annotated example of a data
8* file can be obtained by deleting the first 3 characters from the
9* following 22 lines:
10* 'CBLAT3.SNAP' NAME OF SNAPSHOT OUTPUT FILE
11* -1 UNIT NUMBER OF SNAPSHOT FILE (NOT USED IF .LT. 0)
12* F LOGICAL FLAG, T TO REWIND SNAPSHOT FILE AFTER EACH RECORD.
13* F LOGICAL FLAG, T TO STOP ON FAILURES.
14* T LOGICAL FLAG, T TO TEST ERROR EXITS.
15* 2 0 TO TEST COLUMN-MAJOR, 1 TO TEST ROW-MAJOR, 2 TO TEST BOTH
