DBLAT3

Purpose:

 Test program for the DOUBLE PRECISION 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 6 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 20 lines:
 'dblat3.out'      NAME OF SUMMARY OUTPUT FILE
 6                 UNIT NUMBER OF SUMMARY FILE
 'DBLAT3.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 1.0 0.7       VALUES OF ALPHA
 3                 NUMBER OF VALUES OF BETA
 0.0 1.0 1.3       VALUES OF BETA
 DGEMM  T PUT F FOR NO TEST. SAME COLUMNS.
 DSYMM  T PUT F FOR NO TEST. SAME COLUMNS.
 DTRMM  T PUT F FOR NO TEST. SAME COLUMNS.
 DTRSM  T PUT F FOR NO TEST. SAME COLUMNS.
 DSYRK  T PUT F FOR NO TEST. SAME COLUMNS.
 DSYR2K T PUT F FOR NO TEST. SAME COLUMNS.
