LAPACK is a library of Fortran 77 routines for solving the most commonly occurring problems in linear algebra. It has been designed to be efficient on a wide body of modern high-performance computers. The name LAPACK is an acronym for Linear Algebra PACKage.

LAPACK includes driver routines for solving standard types of problems, computational routines for performing distinct computational tasks, and auxiliary routines for performing certain subtasks or low-level computations.
