(//) :: Enum c => Array c -> [(Point, c)] -> Array c Source

Construct an array updated with the association list.

replicateMA :: Enum c => Monad m => X -> Y -> m c -> m (Array c) Source

Create an array from a replicated monadic action.

generateMA :: Enum c => Monad m => X -> Y -> (Point -> m c) -> m (Array c) Source

Create an array from a monadic function.

ifoldlA :: Enum c => (a -> Point -> c -> a) -> a -> Array c -> a Source

Fold left strictly over an array (function applied to each element and its index).

imapA :: (Enum c, Enum d) => (Point -> c -> d) -> Array c -> Array d Source

Map over an array (function applied to each element and its index).

mapWithKeyM_A :: Enum c => Monad m => (Point -> c -> m ()) -> Array c -> m () Source

Map monadically over an array (function applied to each element and its index) and ignore the results.

minIndexA :: Enum c => Array c -> Point Source

Yield the point coordinates of a minimum element of the array. The array may not be empty.

minLastIndexA :: Enum c => Array c -> Point Source

Yield the point coordinates of the last minimum element of the array. The array may not be empty.

maxIndexA :: Enum c => Array c -> Point Source

Yield the point coordinates of the first maximum element of the array. The array may not be empty.

maxLastIndexA :: Enum c => Array c -> Point Source

Yield the point coordinates of the last maximum element of the array. The array may not be empty.
