There is one prototype of tbsv
            available, please see below. 
tbsv( const int_t k, const MatrixA& a, VectorX& x );
            tbsv (short for triangular,
            banded, solve system of equations) provides a C++ interface to BLAS routines
            STBSV, DTBSV, CTBSV, and ZTBSV. tbsv
            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 band matrix, with ( k + 1 ) diagonals.
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 MatrixA.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixA>::type. Table X below illustrates to
            which specific routine this dispatching will take place.
          
Table 1.72. Dispatching of tbsv.
| Value type of MatrixA | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | STBSV | cblas_stbsv | cublasStbsv | 
| 
                       | DTBSV | cblas_dtbsv | Unavailable | 
| 
                       | CTBSV | cblas_ctbsv | cublasCtbsv | 
| 
                       | ZTBSV | cblas_ztbsv | Unavailable | 
            The original routines STBSV, DTBSV, CTBSV, and ZTBSV have nine arguments,
            whereas tbsv requires
            three arguments.
