Memoization combinators are great for providing high-performance Haskell programs, but they can be even faster if memoization is performed on a finite, discrete domain since an array can then be used to store results.
This package provides various combinators for doing just this, including also combinators for quanitzing and discretizing Float/Double-valued functions.
