getrs
Prototype

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

getrs( const MatrixA& a, const VectorIPIV& ipiv, MatrixB& b );

Description

getrs (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGETRS, DGETRS, CGETRS, and ZGETRS. getrs solves a system of linear equations A * X = B, A*T * X = B, or A*H * X = B with a general N-by-N matrix A using the LU factorization computed by ZGETRF.

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.
