Ceres docs advocate for using algorithmic differentiation instead of finite differences. Let's make one more IPy notebook example with the jacobian calculated using algopy, https://pythonhosted.org/al…

SRP-6 is the currently most widely deployed augmented PAKE algorithm, based on a key exchange based on finite-field Diffie-Hellmann arithmetic.
An early version is defined in RFC 2945, the SRP-6 de…

For the samplers which use derivatives (HMC, NUTS, ...), is it possible to use AD instead of finite differences? Even doing it manually (calculating the derivative with eg `ForwardDiff.jl` and supplyi…

**Is your feature request related to a problem? Please describe.**
I'm working on a project where it's important to estimate higher-order derivatives (e.g. 2nd, 3rd, 4th, and potentially mixed)…

Implement a way to compute automatically the bulk modulus for the variable cell relaxation, if a calculator is provided, by using finite-differences of pressure at two volumes.

The fact that `Finite n` represents a natural number in the *open* range [0, *n*), equivalent to the closed range [0, *n* − 1] rather than the closed range [0, *n*], seems to be a consistent source of…

The "pyrely.performance" subpackage should provide the API for performance functions (scalar output only in a first time). The following features need to be studied:
- Should the user provide a classi…

Hi,
Would it be possible to extent test.py to show how to use finite differences to check the backward implementation? Or is there any other resource on this topic than the test directory in the main…
