Summary

Decorator that caches the value and derivative(s) of function each time it is called.

Extended Summary

This is a simplistic memoizer that calls and caches a single value of f(x, *args). It assumes that args does not change between invocations. It supports the use case of a root-finder where args is fixed, x changes, and only rarely, if at all, does x assume the same value more than once.
