There is one prototype of larre
            available, please see below. 
larre( const char range, const int_t n, Scalar >, Scalar >, const int_t il, const int_t iu, VectorD& d, VectorE& e, VectorE2& e2, const Scalar >, const Scalar >, const Scalar >, int_t& nsplit, VectorISPLIT& isplit, int_t& m, VectorW& w, VectorWERR& werr, VectorWGAP& wgap, VectorIBLOCK& iblock, VectorINDEXW& indexw, VectorGERS& gers, Scalar > );
            larre (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SLARRE and DLARRE. To find
            the desired eigenvalues of a given real symmetric tridiagonal matrix
            T, larre sets any "small"
            off-diagonal elements to zero, and for each unreduced block T_i, it finds
            (a) a suitable shift at one end of the block's spectrum, (b) the base
            representation, T_i - sigma_i I = L_i D_i L_i^T, and (c) eigenvalues
            of each L_i D_i L_i^T. The representations and eigenvalues found are
            then used by DSTEMR to compute the eigenvectors of T. The accuracy varies
            depending on whether bisection is used to find a few eigenvalues or the
            dqds algorithm (subroutine DLASQ2) to conpute all and then discard any
            unwanted one. As an added benefit, larre
            also outputs the n Gerschgorin intervals for the matrices L_i D_i L_i^T.
          
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type VectorD.
            The type of values is obtained through the value_type
            meta-function typename value_type<VectorD>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
