There is one prototype of heevx
            available, please see below. 
heevx( const char jobz, const char range, MatrixA& a, const Scalar >, const Scalar >, const int_t il, const int_t iu, const Scalar >, int_t& m, VectorW& w, MatrixZ& z, VectorIFAIL& ifail );
            heevx (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSYEVX, DSYEVX, CHEEVX, and
            ZHEEVX. heevx computes
            selected eigenvalues and, optionally, eigenvectors of a complex Hermitian
            matrix A. Eigenvalues and eigenvectors can be selected by specifying
            either a range of values or a range of indices for the desired eigenvalues.
          
            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.
