There is one prototype of gbcon
            available, please see below. 
gbcon( const char norm, const MatrixAB& ab, const VectorIPIV& ipiv, const Scalar >, Scalar > );
            gbcon (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGBCON, DGBCON, CGBCON, and
            ZGBCON. gbcon estimates
            the reciprocal of the condition number of a complex general band matrix
            A, in either the 1-norm or the infinity-norm, using the LU factorization
            computed by ZGBTRF.
          
An estimate is obtained for norm(inv(A)), and the reciprocal of the condition number is computed as RCOND = 1 / ( norm(A) * norm(inv(A)) ).
            The selection of the LAPACK routine is done during compile-time, and
            is determined by the type of values contained in type MatrixAB.
            The type of values is obtained through the value_type
            meta-function typename value_type<MatrixAB>::type. The dispatching table below illustrates
            to which specific routine the code path will be generated.
