[SciPy-user] Numerical gradient approximation on matrix

Hi all,

 

I have a two-dimensional array from which I wish to compute the gradient
(i.e. the slope against the first and second dimension). With Matlab, I can
do it easily using the gradient.m function. Is there something similar in
Scipy or matplotlib? I've browsed the documentation but couldn't found
anything but approximate gradient computations on functions in the optimize
module. Nothing about computations on matrices.

 

Thank you for your help,

 

Dimitri
