There is one prototype of getri
            available, please see below. 
getri( MatrixA& a, const VectorIPIV& ipiv );
            getri (short for $FRIENDLY_NAME)
            provides a C++ interface to LAPACK routines SGETRI, DGETRI, CGETRI, and
            ZGETRI. getri computes
            the inverse of a matrix using the LU factorization computed by ZGETRF.
          
This method inverts U and then computes inv(A) by solving the system inv(A)*L = inv(U) for inv(A).
            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.
