NAME

       x{s,d,c,z}c?blat{1,2,3} - testing programs for blas

SYNOPSIS

       x{s,d,c,z}c?blat1
       x{s,d,c,z}c?blat{2,3} < parameter file

DESCRIPTION

       This  manual  page  documents  briefly  the  blas  testing programs.  This manual page was
       written for the Debian GNU/Linux distribution because the original programs  do  not  have
       manual pages.

       blas  is  a  library  of  Basic Linear Algebra routines, accessed through either a Fortran
       and/or a C interface.  These routines are categorized into three levels: level1  referring
       to  vecotr-vector  operations,  level2  to matrix-vector operations, and level3 to matrix-
       matrix operations.   In addition, all routines are written in  four  "precisions",  single
       precision  real  (s),  double precision real (d), cingle precision complex (c), and double
       precision complex (z).
       The testing binaries examine routines in the level indicated by the last character in  the
       program  name  and in the precision indicated by the second character in the program name.
       The stem "blat" in the program name refers  to  a  Fortran  interface  tester,  whereas  a
       "cblat" stem refers to a C interface tester.
       The  test  programs  for  levels  2  and 3 read a set of parameters specifying the problem
       ranges to examine on standard input.  Sample input files are found in /usr/share/doc/blas-
       test/examples.   Files  of  the  form {s,d,c,z}in{2,3} are input files for the C interface
       testing programs, while files or the form  {s,d,c,z}blat{2,3}d  are  input  files  to  the
       Fortran testing programs.
       On  Debian  systems, these programs are dynamically linked against the blas library.  This
       enables the user to test and compare alternate versions of  the  library,  such  as  those
       provided  by  atlas,  through  the  use  of the LD_LIBRARY_PATH and LD_PRELOAD environment
       variables.  One can confirm the  versions  of  the  libraries  being  tested  in  a  given
       environment with the aid of the ldd program.

OPTIONS

       These programs take no command line options.
