Data.Repa.Array.Material.Unboxed

Documentation

data U

Layout an array as a flat vector of unboxed elements.

This is the most efficient representation for numerical data.

The implementation uses Data.Vector.Unboxed which picks an efficient, specialised representation for every element type. In particular, unboxed vectors of pairs are represented as pairs of unboxed vectors.

UNSAFE: Indexing into raw material arrays is not bounds checked. You may want to wrap this with a Checked layout as well.
