template<class TYPE>
    void inverse(TTensor<TYPE, 1u, 1u> &m); // Inverse 1x1 tensor(matrix) 
    
    template<class TYPE>
    void inverse(TTensor<TYPE, 2u, 2u> &m); // Inverse 2x2 tensor(matrix) 
    
    template<class TYPE, size_t SIZE>
    typename std::enable_if<(SIZE > 2), void>::type inverse(TTensor<TYPE, SIZE, SIZE> &m); // Inverse NxN tensor(matrix)
