There is one prototype of trrfs
available, please see below.
trrfs( const MatrixA& a, const MatrixB& b, const MatrixX& x, VectorFERR& ferr, VectorBERR& berr );
trrfs (short for $FRIENDLY_NAME)
provides a C++ interface to LAPACK routines STRRFS, DTRRFS, CTRRFS, and
ZTRRFS. trrfs provides
error bounds and backward error estimates for the solution to a system
of linear equations with a triangular coefficient matrix.
The solution matrix X must be computed by ZTRTRS or some other means
before entering this routine. trrfs
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 MatrixA.
The type of values is obtained through the value_type
meta-function typename value_type<MatrixA>::type. The dispatching table below illustrates
to which specific routine the code path will be generated.
