Description

I want to try and use diffrax to simulate some correlated ("directional") noise in a 3D oscillator i.e. solving the following SDEs

image

I couldn’t parse from the docs what kind of solver would treat the noise term as a matrix and the dW term as a vector of Wiener processes, at the same time.

Does diffrax have such a solver / can I build one from what diffrax offers?

Research direction

Start with the Diffrax documentation and the solver-related material to determine whether a matrix noise term and vector of Wiener processes are already supported. Done means establishing whether an existing solver applies, or documenting a concrete implementation path using the capabilities Diffrax exposes.
