Constructors

Matrix a (Map ix a)

Instances

Functor (Matrix ix)

Size i => Applicative (Matrix i)

(Show a, Size ix, Size (Row ix), Size (Column ix)) => Show (Matrix ix a)

fromAssocList :: (Ord i, Eq a) => a -> [(i, a)] -> Matrix i a

toAssocList :: Matrix i a -> (a, [(i, a)])

(!) :: Ord ix => Matrix ix a -> ix -> a

! looks up an element in the sparse matrix. If the element is not found in the sparse matrix, ! returns the default value.

fill :: Size ix => Matrix ix a -> Matrix ix a

prune :: (Size ix, Eq a) => a -> Matrix ix a -> Matrix ix a

sparse :: (Size ix, Eq a) => a -> Matrix ix a -> Matrix ix a

Make a Matrix sparse, with a default zero value.

mm :: (Size m, Size n, Size m', Size n', n ~ m', Num a) => Matrix (m, n) a -> Matrix (m', n') a -> Matrix (m, n') a

rowSets :: (Size a, Ord b) => Set (a, b) -> Matrix a (Set b)

columnSets :: (Size b, Ord a) => Set (a, b) -> Matrix b (Set a)

transpose :: (Size x, Size y, Eq a) => Matrix (x, y) a -> Matrix (y, x) a

zipWith :: Size x => (a -> b -> c) -> Matrix x a -> Matrix x b -> Matrix x c
