program dblat2 ( )

DBLAT2

Purpose:
 Test program for the DOUBLE PRECISION 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 16 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 34 lines:
 'dblat2.out'      NAME OF SUMMARY OUTPUT FILE
 6                 UNIT NUMBER OF SUMMARY FILE
 'DBLAT2.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 1.0 0.7       VALUES OF ALPHA
