What you need to know to use these subprograms
Table 3-4 shows the valid combinations of T, XX, and Y, YY, or YYY. Each line
indicates the allowable T prefixes and Y, YY, or YYY suffixes for a particular
root name XX.
Table 3-4 Extended BLAS Naming Convention—Subprogram Names
The subprograms SGEMMS, DGEMMS, CGEMMS, and ZGEMMS, although
not part of the standard Extended BLAS, are consistent with this
nomenclature.
Operator arguments in the BLAS Standard
Some routines in the BLAS Standard take input-only arguments called
operators. Operators allow for the specification of multiple related operations to
be performed by a single function. The BLAS Standard specifies the type and
the valid values these arguments should have according to the specific
programming language.
Operator arguments used by the BLAS Standard routines are NORM, SORT,
SIDE, UPLO, TRANS, CONJ, DIAG
, and JROT. Refer to “Operator arguments”
on page 25 for explanations of the valid operator values.
In BLAS Standard routines, you specify an operator argument with a named
constant value. The actual numeric value assigned to the named constant is
defined in the appropriate language’s include file. Operator arguments are
represented in the Fortran 77 interface as INTEGERs. This specification is
different from the legacy BLAS, where operator arguments are defined as
CHARACTER*1.
Refer to individual routines in “BLAS Standard routines” on page 339 for the
named constants you can use to specify operator arguments for basic matrix
subprograms.
