type IOMatrix = MMatrix RealWorld

type STMatrix s = MMatrix s

new :: PrimMonad m => Int -> Int -> m (MMatrix (PrimState m))

Creates a mutable matrix of the given dimension. Elements are initialized with 0.

set :: PrimMonad m => MMatrix (PrimState m) -> Double -> m ()

Set all elements of the matrix to the given value

read :: PrimMonad m => MMatrix (PrimState m) -> Int -> Int -> m Double

Yield the element at the given position.

write :: PrimMonad m => MMatrix (PrimState m) -> Int -> Int -> Double -> m ()

Replace the element at the given position.
