Minimal complete definition

Methods

dim :: m v a -> (Int, Int) Source #

unsafeIndex :: m v a -> (Int, Int) -> a Source #

unsafeFromVector :: (Int, Int) -> v a -> m v a Source #

flatten :: m v a -> v a Source #

Default algorithm is O((m*n) * O(unsafeIndex)).

unsafeTakeRow :: m v a -> Int -> v a Source #

Extract a row. Default algorithm is O(n * O(unsafeIndex)).

unsafeTakeColumn :: m v a -> Int -> v a Source #

Extract a column. Default algorithm is O(m * O(unsafeIndex)).

takeDiag :: m v a -> v a Source #

Extract the diagonal. Default algorithm is O(min(m,n) * O(unsafeIndex)).

thaw :: PrimMonad s => m v a -> s (Mutable m (Mutable v) (PrimState s) a) Source #

unsafeThaw :: PrimMonad s => m v a -> s (Mutable m (Mutable v) (PrimState s) a) Source #
