Does anybody know how can I get the "gradient" of a list of points?
My real problem is:
I have a scalar field previously obtained numerically that for a
given point (xi,yi) takes a value f(xi,yi). What I want to do is an
estimation of the gradient of this scalar field BUT I haven't got any
analytical function that expresses my field so I can't use the Grad
How can I solve this using Mathematica?
Thanks in advance
