There is one prototype of sygv
            available, please see below. 
sygv( const int_t itype, const char jobz, MatrixA& a, MatrixB& b, VectorW& w );
            sygv (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSYGV and DSYGV. sygv computes all the eigenvalues,
            and optionally, the eigenvectors of a real generalized symmetric-definite
            eigenproblem, of the form A*x(lambda)*B*x, A*Bx(lambda)*x,
            or B*A*x=(lambda)*x. Here A and B are assumed to be symmetric and B is
            also positive definite.
          
            The selection of the LAPACK 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. The dispatching table below illustrates
            to which specific routine the code path will be generated.
