program SBLAT2¶

SBLAT2

Purpose:

!>
!> Test program for the REAL 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:
!> 'sblat2.out'      NAME OF SUMMARY OUTPUT FILE
!> 6                 UNIT NUMBER OF SUMMARY FILE
!> 'SBLAT2.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
