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.
