Synopsis

data C
data family Array r sh e
makeCursored :: sh -> (sh -> cursor) -> (sh -> cursor -> cursor) -> (cursor -> e) -> Array C sh e

Documentation

data C Source #

Cursored Arrays. These are produced by Repa's stencil functions, and help the fusion framework to share index compuations between array elements.

The basic idea is described in ``Efficient Parallel Stencil Convolution'', Ben Lippmeier and Gabriele Keller, Haskell 2011 -- though the underlying array representation has changed since this paper was published.
