Description

  Basic Linear Algebra Subroutines Level 1 Sparse (BLAS 1S) are a part of the
  Compaq Extended Math Library.

  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 BLAS Level 1 Sparse subprograms are sparse extensions of
  BLAS Level 1 subprograms. They are similar in functionality to BLAS Level 1
  subprograms but operate on sparse vectors stored in a compressed form.

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