Description

  Basic Linear Algebra Subroutines Level 1 (BLAS 1) are a part of the Compaq
  Extended Math Library (CXML). The BLAS1 subprograms perform low granularity
  operations on vectors that involve one or two vectors as input and return
  either a vector or a scalar as output. These subprograms have been
  optimized to provide high performance on Alpha systems.

  The following routines are included in BLAS 1. The Subprogram Name is the
  name of the manual page containing documentation on the subprogram.
