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

       lapack  is  a  library of common linear algebra routines, which in turn
       makes use of the basic linear algebra primitives supplied by  the  blas
       application  programming  interface.   In  general,  one cannot use the
       lapack library without a blas compatible library on the system.
       The testing binaries (those with "tst" in the program name)  check  the
       integrity  of  the  eigen and linear equation routines ("eig" and "lin"
       stems in program name, respectively) in each of four precisions: single
       precision  real,  double  precision real, single precision complex, and
       double  precision  complex  (program  suffixes  "s","d","c",  and   "z"
       All  of  these  programs take as input a parameter file which specifies
       the range of matrix sizes and types used in each  test.   Sample  input
       files can be found in /usr/share/doc/lapack-test/examples.
       On  Debian  systems, these programs are dynamically linked against both
       blas and lapack libraries.  This enables the user to test  and  compare
       alternate versions of these libraries, 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.


       These programs take no command line options.
