Native function-based symbolic algebra tools #22
Description
Algebraically transform a given function with solve(), simplify(), derivative(), and integral().
Repo: https://github.com/mitchelloharawild/symbolic
In fabletools and distributional I have a rudimentary solve() implementation which traverses a parsed AST and inverts the expression. This is used for example with back-transforming forecasts, where the transformation needs inverting/solving.
In distributional, there is a need for symbolic derivatives, better symbolic solvers and possibly also integration.
There is some symbolic operations in R, most commonly symbolic derivatives. For example:
stats::deriv()Deriv::Deriv()
Having symbolic expression simplification would also be valuable.
