Data.Array.Repa.Repr.Delayed

Synopsis

Documentation

data D Source #

Delayed arrays are represented as functions from the index to element value.

Every time you index into a delayed array the element at that position is recomputed.

Instances
Source D a Source #

Compute elements of a delayed array.

fromFunction :: sh -> (sh -> a) -> Array D sh a Source #

O(1). Wrap a function as a delayed array.

toFunction :: (Shape sh, Source r1 a) => Array r1 sh a -> (sh, sh -> a) Source #

O(1). Produce the extent of an array, and a function to retrieve an arbitrary element.

delay :: Shape sh => Source r e => Array r sh e -> Array D sh e Source #

O(1). Delay an array. This wraps the internal representation to be a function from indices to elements, so consumers don't need to worry about what the previous representation was.
