Contents

Description

This module defines some basic vector functionality. It uses the same internal data representation as SimpleVec, but declares Vec to be an instance of VectorSpace. We import zeroV, negateV, sumV, ^+^, ^-^ from AdditiveGroup, and *^, ^*, ^/, <.>, magnitude from VectorSpace.

CarrotVec exports exactly the same symbols as SimpleVec; they are just defined differently.
