traverseSource

Arguments

:: forall r sh sh' a b . (Source r a, Shape sh, Shape sh') 
=> Array r sh a

Source array.

-> (sh -> sh')

Function to produce the extent of the result.

-> ((sh -> a) -> sh' -> b)

Function to produce elements of the result. It is passed a lookup function to get elements of the source.

-> Array D sh' b 

Unstructured traversal.

unsafeTraverseSource

Arguments

:: forall r sh sh' a b . (Source r a, Shape sh, Shape sh') 
=> Array r sh a

Source array.

-> (sh -> sh')

Function to produce the extent of the result.

-> ((sh -> a) -> sh' -> b)

Function to produce elements of the result. It is passed a lookup function to get elements of the source.

-> Array D sh' b 

Unstructured traversal.

traverse2Source

Arguments

:: forall r1 r2 sh sh' sh'' a b c . (Source r1 a, Source r2 b, Shape sh, Shape sh', Shape sh'') 
=> Array r1 sh a

First source array.

-> Array r2 sh' b

Second source array.

-> (sh -> sh' -> sh'')

Function to produce the extent of the result.

-> ((sh -> a) -> (sh' -> b) -> sh'' -> c)

Function to produce elements of the result. It is passed lookup functions to get elements of the source arrays.

-> Array D sh'' c 

Unstructured traversal over two arrays at once.

unsafeTraverse2Source

Arguments

:: forall r1 r2 sh sh' sh'' a b c . (Source r1 a, Source r2 b, Shape sh, Shape sh', Shape sh'') 
=> Array r1 sh a

First source array.

-> Array r2 sh' b

Second source array.

-> (sh -> sh' -> sh'')

Function to produce the extent of the result.

-> ((sh -> a) -> (sh' -> b) -> sh'' -> c)

Function to produce elements of the result. It is passed lookup functions to get elements of the source arrays.

-> Array D sh'' c 

Unstructured traversal over two arrays at once.
