PROGRAM ZBLAT3
*
* Test program for the COMPLEX*16 Level 3 Blas.
*
* The program must be driven by a short data file. The first 14 records
* of the file are read using list-directed input, the last 9 records
* are read using the format ( A8, L2 ). An annotated example of a data
* file can be obtained by deleting the first 3 characters from the
* following 23 lines:
* 'ZBLAT3.SUMM' NAME OF SUMMARY OUTPUT FILE
* 6 UNIT NUMBER OF SUMMARY FILE
* 'ZBLAT3.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
* 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
* ZGEMM3M T PUT F FOR NO TEST. SAME COLUMNS.
* ZHEMM T PUT F FOR NO TEST. SAME COLUMNS.
* ZSYMM T PUT F FOR NO TEST. SAME COLUMNS.
* ZTRMM T PUT F FOR NO TEST. SAME COLUMNS.
* ZTRSM T PUT F FOR NO TEST. SAME COLUMNS.
* ZHERK T PUT F FOR NO TEST. SAME COLUMNS.
