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 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" 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/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.
