There is one prototype of tbrfs
available, please see below.
tbrfs( const int_t kd, const MatrixAB& ab, const MatrixB& b, const MatrixX& x, VectorFERR& ferr, VectorBERR& berr );
tbrfs (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines STBRFS, DTBRFS, CTBRFS, and
ZTBRFS. tbrfs provides
error bounds and backward error estimates for the solution to a system
of linear equations with a triangular band coefficient matrix.
The solution matrix X must be computed by ZTBTRS or some other means
before entering this routine. tbrfs
does not do iterative refinement because doing so cannot improve the
backward error.
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.
