Step size adaptation appears to be not working well with Zygote. Unfortunately, I'm not familiar enough with the inner workings of Zygote to see what precisely breaks down. Perhaps @willtebbutt...

Hey @tpapp, How do the results look like it you set `factor` to a high number, e.g. `central_fdm(5, 1; factor=1e4)`?

If `factor=1e6` works fine, then that would be the more robust solution, I think. `factor` controls how much error derives from the function evaluations and is relative to the machine...

Hey @tpapp! Would you be able to confirm whether you've found a satisfactory way to compute finite differences? If so, we'll add a recommendation to the README. :)

Thanks for responding quickly! No need to rush at all, of course. :)

That's fantastic to hear! I've opened a PR to add a small section to the README (#174).

Perhaps a bit of an old issue, but just wanted to remark that there is also the solution of using `forward_fdm` instead of `central_fdm`: ```julia julia> x = randn(2, 2);...

Hey @thudjx! Would you be able to share the function you're trying to estimate the derivative of? To answer your questions, `max_range` specifies the maximum distance from `x` that the...

Thanks for uploading the function! I've played around with it, and it seems like a derivative which is really hard to estimate. To try to get somewhere, I ran a...

> Physically, the result of derivative should have finite value only at its 74 or 75 components, and all other components should be close to zero. Ah, it seems that...
