Data.Array.Repa.Repr.Unboxed

Synopsis

Documentation

data U Source

Unboxed arrays are represented as unboxed vectors.

The implementation uses Data.Vector.Unboxed which is based on type families and picks an efficient, specialised representation for every element type. In particular, unboxed vectors of pairs are represented as pairs of unboxed vectors. This is the most efficient representation for numerical data.
