convert Eigen Tensor to a Matrix

int main () {
    Eigen::Tensor<double,4> my_rank4 (2,2,2,2);
    my_rank4.setRandom();

    Eigen::MatrixXd         mymatrix =  Tensor_to_Matrix(my_rank4, 4,4);
    Eigen::Tensor<double,3> my_rank3 =  Matrix_to_Tensor(mymatrix, 2,2,4);

    std::cout << my_rank3 << std::endl;

    return 0;
}
