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

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

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

Set all elements of the matrix to the given value

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

Yield the element at the given position.

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

Replace the element at the given position.
