Prototype

There is one prototype of gerfs available, please see below.

gerfs( const MatrixA& a, const MatrixAF& af, const VectorIPIV& ipiv,
        const MatrixB& b, MatrixX& x, VectorFERR& ferr, VectorBERR& berr );

Description

gerfs (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGERFS, DGERFS, CGERFS, and ZGERFS. gerfs improves the computed solution to a system of linear equations and provides error bounds and backward error estimates for the solution.

The selection of the LAPACK routine is done during compile-time, and is determined by the type of values contained in type MatrixA. The type of values is obtained through the value_type meta-function typename value_type<MatrixA>::type. The dispatching table below illustrates to which specific routine the code path will be generated.

Definition

Defined in header boost/numeric/bindings/lapack/computational/gerfs.hpp.

Example

#include <boost/numeric/bindings/lapack/computational/gerfs.hpp>
using namespace boost::numeric::bindings;

lapack::gerfs( x, y, z );

this will output
