Hi, I am trying to achieve the following:
>>> f = Function('f')(M,x)
>>> f = M[x+1] - M[x]
>>> F = lambdify(f)
>>> print F(np.array([5,2,1]),1)
>>> 3
What would be the best way to do it?
By the way this is part of a bigger goal i.e. discretize derivatives of
arbitrary order, but I am totally a newbie and I have to go step by step...
(See my post here:
