Description

  Basic Linear Algebra Subroutines Level 1 Extensions (BLAS 1E) 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.  The original BLAS
  Level 1 subprograms have been enhanced by the addition of the BLAS1
  extensions which also perform vector-vector operations.

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