PROGRAM CBLAT2
*
*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> Test
program for the
COMPLEX 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 17 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 35 lines:
*>
'cblat2.out' NAME OF SUMMARY OUTPUT
FILE
*> 6
UNIT NUMBER OF SUMMARY
FILE
*>
'CBLA2T.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
