I have the following code
pub fn lie_jacobian(generator_x: Matrix3x4<MatrixData>,
generator_y: Matrix3x4<MatrixData>,
generator_z: Matrix3x4<MatrixData>,
generator_roll: Matrix3x4<MatrixData>,
generator_pitch: Matrix3x4<MatrixData>,
generator_yaw: Matrix3x4<MatrixData>,
Y_est: DMatrix<MatrixData>) > () {
let N = Y_est.ncols();
let G_1_y = generator_x*Y_est;
let G_1_y_stacked = stack(G_1_y);
let G_2_y = generator_y*Y_est;
let G_2_y_stacked = stack(G_2_y);
....
Since DMatrix does not implement the copy trait I get the following error
error[E0382]: use of moved value: `Y_est`

48  Y_est: DMatrix<MatrixData>) > () {
  move occurs because `Y_est` has type `image::na::Matrix<f64, image::na::Dynamic, image::na::Dynamic, image::na::VecStorage<f64, image::na::Dynamic, image::na::Dynamic>>`, which does not implement the `Copy` trait
...
51  let G_1_y = generator_x*Y_est;
  value moved here
...
54  let G_2_y = generator_y*Y_est;
 ^^^^^ value used here after move
Matrix multiplication is not mutable, so in theory I should be able to reuse Y_est
without cloning(?). Or maybe a different way of asking. Does clone()
on a DMatrix perform a deep copy?
