##### gbtrs

###### 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.

Table 1.242. Dispatching of gbtrs

Value type of MatrixAB | LAPACK routine
--- | ---
`float` | SGBTRS
`double` | DGBTRS
`complex<float>` | CGBTRS
`complex<double>` | ZGBTRS
