AP_NavEKF3: derivation: pin generator library versions Document exactly which versions were used when generating the code. Sympy is the most important so it is explicitly checked. Also add an alternate generate script which uses `nix-shell` to make it convenient to automatically use these versions. 2024-08-11 16:02:05 -03:00			`#!/usr/bin/env nix-shell`

AP_NavEKF3: document provenance of yaw fusion equations Requires digging up old versions of the generator script. The equations have been rearranged somewhat after generation to choose the appropriate method but they do match overall. The auto-substitution of the power functions caused slight changes to the generated syntax so we make those to the real code as well. Delete `yaw_generated.cpp` as we know exactly how to generate it now. 2024-08-11 16:30:26 -03:00			`python3 ./generate_2.py`
