SYNOPSIS
x{eig,lin}{tst,tim}{s,d,c,z} < parameter file
DESCRIPTION
- This manual page documents briefly the lapack testing and
- timing 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 gen
- eral, 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 rou
- tines ("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" respectively). In like
- manner, the timing routines (those with "tim" in the program
- name) measure performance in the above classes of routines.
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/ex
- amples.
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 ver
- sions of the libraries being tested in a given environment with
- the aid of the ldd program.
OPTIONS
These programs take no command line options.
