Data.Geometry.Vector.VectorFamily

Implementation of \(d\)-dimensional vectors. The implementation automatically selects an optimized representation for small (up to size 4) vectors.

d dimensional Vectors

newtype Vector (d :: Nat) (r :: *)

Datatype representing d dimensional vectors. The default implementation is based n VectorFixed. However, for small vectors we automatically select a more efficient representation.
