Prototype

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

gbtrs( const MatrixAB& ab, const VectorIPIV& ipiv, MatrixB& b );

Description

gbtrs (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGBTRS, DGBTRS, CGBTRS, and ZGBTRS. gbtrs solves a system of linear equations A * X = B, A*T * X = B, or A*H * X = B with a general band matrix A using the LU factorization computed by ZGBTRF.

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