Subprograms for basic vector operations

Subprograms for basic vector operations

The following sections in this chapter describe the vector subprograms included with VECLIB:

Legacy BLAS routines

BLAS Standard routines

Note that the specification for operator arguments is different in legacy BLAS routines than in BLAS Standard routines. Operator arguments are represented in the BLAS Standard Fortran 77 interface as INTEGERs; in the legacy BLAS they are defined as CHARACTER*1.

In BLAS Standard routines, you specify an operator argument with a named constant value. Refer to the individual routines in “BLAS Standard routines” on page 152 for the named constants you can use to specify operator arguments. The actual numeric value assigned to the named constant is defined in the f77blas.h include file.
