Algorithmically this means that given :math:`y`, compute :math:`x =
f^{-1}(y)` by whatever means you can. Evaluate the Jacobian of
:math:`f` at :math:`x`. If the Jacobian matrix is invertible, then
- the inverse is the Jacobian of the inverse at :math:`y`.
+ its inverse is the Jacobian of :math:`f^{-1}(y)` at :math:`y`.
One can put this into practice with the following code fragment.
