There is one prototype of gtrfs
            available, please see below. 
gtrfs( const VectorDL& dl, const VectorD& d, const VectorDU& du, const VectorDLF& dlf, const VectorDF& df, const VectorDUF& duf, const VectorDU2& du2, const VectorIPIV& ipiv, const MatrixB& b, MatrixX& x, VectorFERR& ferr, VectorBERR& berr );
            gtrfs (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGTRFS, DGTRFS, CGTRFS, and
            ZGTRFS. gtrfs improves
            the computed solution to a system of linear equations when the coefficient
            matrix is tridiagonal, 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 VectorDL.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorDL>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
