Instances

(Source D e, Shape DIM2, Elt e) => LoadRange D DIM2 e

Compute a range of elements in a rank-2 array.

(Source C e, Shape DIM2, Elt e) => LoadRange C DIM2 e

Compute a range of elements in a rank-2 array.

(Source C e, Shape DIM2, Elt e) => Load C DIM2 e

Compute all elements in an rank-2 array.

(Eq tail, Eq head) => Eq (:. tail head) 
(Eq (:. tail head), Ord tail, Ord head) => Ord (:. tail head) 
(Read tail, Read head) => Read (:. tail head) 
(Show tail, Show head) => Show (:. tail head) 
(Eq (:. sh Int), Shape sh) => Shape (:. sh Int) 
Slice sl => Slice (:. sl All) 
Slice sl => Slice (:. sl Int) 

Common dimensions.

type DIM0 = ZSource

ix1 :: Int -> DIM1Source

Helper for index construction.

Use this instead of explicit constructors like (Z :. (x :: Int)). The this is sometimes needed to ensure that x is constrained to be in Int.

ix3 :: Int -> Int -> Int -> DIM3Source

ix4 :: Int -> Int -> Int -> Int -> DIM4Source

ix5 :: Int -> Int -> Int -> Int -> Int -> DIM5Source
