There are two prototypes of trmm
            available, please see below. 
trmm( const Side side, const Scalar >, const MatrixA& a, MatrixB& b );
trmm( const Side side, const Scalar alpha, const MatrixA& a, MatrixB& b );
            trmm (short for triangular
            matrix-matrix operation) provides a C++ interface to BLAS routines STRMM,
            DTRMM, CTRMM, and ZTRMM. trmm
            performs one of the matrix-matrix operations
          
B := alpha*op( A )*B, or B := alpha*B*op( A )
where alpha is a scalar, B is an m by n matrix, A is a unit, or non-unit, upper or lower triangular matrix and op( A ) is one of
op( A ) = A or op( A ) = A' or op( A ) = conjg( A' ).
            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 1.96. Dispatching of trmm.
| Value type of MatrixA | BLAS routine | CBLAS routine | CUBLAS routine | 
|---|---|---|---|
| 
                       | STRMM | cblas_strmm | cublasStrmm | 
| 
                       | DTRMM | cblas_dtrmm | cublasDtrmm | 
| 
                       | CTRMM | cblas_ctrmm | cublasCtrmm |

                       | ZTRMM | cblas_ztrmm | Unavailable | 
            The original routines STRMM, DTRMM, CTRMM, and ZTRMM have eleven arguments,
            whereas trmm requires
            four arguments.
