Prototype

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

gbtrf( MatrixAB& ab, VectorIPIV& ipiv );

Description

gbtrf (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SGBTRF, DGBTRF, CGBTRF, and ZGBTRF. gbtrf computes an LU factorization of a complex m-by-n band matrix A using partial pivoting with row interchanges.

This is the blocked version of the algorithm, calling Level 3 BLAS.

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.

Definition

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