We need this type class to distinguish between different tuples of Ix. There are Shapable instances for homogenous Int tuples, but may Haddock doesn't see them.

Methods

sRank :: i -> Int Source

sShape :: i -> i -> [Int]Source

sBounds :: [Int] -> (i, i)Source

Instances

Shapable Int
Shapable (Int, Int)
Shapable (Int, Int, Int)
Shapable (Int, Int, Int, Int)
Shapable (Int, Int, Int, Int, Int)
Shapable (Int, Int, Int, Int, Int, Int)
Shapable (Int, Int, Int, Int, Int, Int, Int)
Shapable (Int, Int, Int, Int, Int, Int, Int, Int)
Shapable (Int, Int, Int, Int, Int, Int, Int, Int, Int)

rank :: (Shapable i, Ix i, IArray a e) => a i e -> Int Source

Determine the rank of an array.

shape :: (Shapable i, Ix i, IArray a e) => a i e -> [Int]Source

Canonical representation of the shape. The following properties hold: 'length . shape = rank' 'product . shape = size'

shapeToStride :: [Int] -> [Int]Source

How much the offset changes when you move one element in the given direction. Since arrays are in row-major order, 'last . shapeToStride = const 1'

size :: (Ix i, IArray a e) => a i e -> Int Source

Number of elements in the Array.
