There is one prototype of steqr
            available, please see below. 
steqr( const char compz, VectorD& d, VectorE& e, MatrixZ& z );
            steqr (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SSTEQR, DSTEQR, CSTEQR, and
            ZSTEQR. steqr computes
            all eigenvalues and, optionally, eigenvectors of a symmetric tridiagonal
            matrix using the implicit QL or QR method. The eigenvectors of a full
            or band complex Hermitian matrix can also be found if ZHETRD or ZHPTRD
            or ZHBTRD has been used to reduce this matrix to tridiagonal form.
          
            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.
