A dynamic programming helper library. It provides some simple APIs to mutable 2 dimensional arrays using Data.Vector.Mutable from the vector package.
This is essential for BOTTOM UP dynamic programming. It is fairly well documented to use laziness and other fancy tricks for memoized top-down dynamic programming in Haskell.
make_matrix :: a -> Int -> Int -> m (MVector (MVector a))
read_matrix :: MVector (MVector a) -> Int -> Int -> m a
write_matrix :: MVector (MVector a) -> Int -> Int -> a -> m ()
m can be either IO or ST depending on your use case.Taken from here : http://www.seas.upenn.edu/~cis552/current/lectures/soln/STMonad.html
The library also contains solutions to various dynamic programming problems in a bottom up style.
