After reading Aaron's recommendation about looking for unanswered sympy
questions at stackoverflow I stumbled upon:
http://stackoverflow.com/questions/18701290/derivatives-discretization-with-sympy
I implemented a solution for this and it is available as a WIP PR over here:
https://github.com/sympy/sympy/pull/7382
I would love to hear your feedback on this.
Hi,
From the stackoverflow question here is your example:
> Here is an example:
>>> from sympy import symbols, Function
>>> x, h = symbols('x h')
>>> f = Function('f')
>>> print(f(x).diff(x).as_finite_diff())
-f(-h + x)/(2*h) + f(h + x)/(2*h)
Is it means that you use "h" symbol from the global namespace?
