## Linear Algebra

This chapter describes functions for solving linear systems. The
library provides simple linear algebra operations which operate directly
on the `gsl_vector`

and `gsl_matrix`

objects. These are
intended for use with "small" systems where simple algorithms are
acceptable.

Anyone interested in large systems will want to use the sophisticated
routines found in LAPACK. The Fortran version of LAPACK is
recommended as the standard package for large-scale linear algebra. It
supports blocked algorithms, specialized data representations and other
optimizations.

The functions described in this chapter are declared in the header file
`gsl_linalg.h`

.
