There is one prototype of trsna
            available, please see below. 
trsna( const char job, const char howmny, const VectorSELECT& select, const MatrixT& t, const MatrixVL& vl, const MatrixVR& vr, VectorS& s, VectorSEP& sep, const int_t mm, int_t& m, const int_t ldwork );
            trsna (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines STRSNA, DTRSNA, CTRSNA, and
            ZTRSNA. trsna estimates
            reciprocal condition numbers for specified eigenvalues and/or right eigenvectors
            of a complex upper triangular matrix T (or of any matrix QT*Q*H
            with Q unitary).
          
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type VectorSELECT.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorSELECT>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
