Riemannian Manifold HMC

[kskyten]

You mentioned having a toy implementation for RHMC. Is the code available somewhere? I would like to experiment with it using higher order AD for matrix expressions.

The code is now dated and not very clean, I think you are better off implementing

directly. If you can obtain higher-order derivatives in a practical way, I would be happy to integrate this method into this package.
