What are contexts

Contexts allow us to provide a Width, Depth, and a coefficient field for a tensor. They also provide access to the Baker-Campbell-Hausdorff formula.

How do contexts fit into RoughPy

Contexts are the environment in which calculations are done. They are used everywhere in RoughPy, for any stream or algebraic object.

How to work with contexts

We can create contexts for Streams in the following way. The example below has width 2, depth 6, and coefficients over the Reals.

context = roughpy.get_context(width=2, depth=6, coeffs=rp.DPReal)
