Prototype

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

pbrfs( const MatrixAB& ab, const MatrixAFB& afb, const MatrixB& b,
        MatrixX& x, VectorFERR& ferr, VectorBERR& berr );

Description

pbrfs (short for $FRIENDLY_NAME) provides a C++ interface to LAPACK routines SPBRFS, DPBRFS, CPBRFS, and ZPBRFS. pbrfs improves the computed solution to a system of linear equations when the coefficient matrix is Hermitian positive definite and banded, 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 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.
