There is one prototype of tpsv
            available, please see below. 
tpsv( const MatrixAP& ap, VectorX& x );
            tpsv (short for triangular,
            packed, solve system of equations) provides a C++ interface to BLAS routines
            STPSV, DTPSV, CTPSV, and ZTPSV. tpsv
            solves one of the systems of equations
          
A*x = b, or A'*x = b, or conjg( A' )*x = b,
where b and x are n element vectors and A is an n by n unit, or non-unit, upper or lower triangular matrix, supplied in packed form.
No test for singularity or near-singularity is included in this routine. Such tests must be performed before calling this routine.
            The selection of the BLAS routine is done during compile-time, and is
            determined by the type of values contained in type MatrixAP.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixAP>::type. Table X below illustrates to
            which specific routine this dispatching will take place.
          
Table 1.76. Dispatching of tpsv.
| Value type of MatrixAP | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | STPSV | cblas_stpsv | cublasStpsv |

                       | DTPSV | cblas_dtpsv | Unavailable | 
| 
                       | CTPSV | cblas_ctpsv | cublasCtpsv |

                       | ZTPSV | cblas_ztpsv | Unavailable | 
            The original routines STPSV, DTPSV, CTPSV, and ZTPSV have seven arguments,
            whereas tpsv requires
            two arguments.
