Type Parameters:

A - the absolute quantity type

Q - the corresponding relative quantity type

implements AbsVector.Row<AbsVector1<A,Q>,Q>

AbsVector1 implements a vector with one real-valued entry representing an absolute quantity. The vector is immutable, except for the display unit, which can be changed. Some of the method that have been defined already for a generic vector have been re-implemented for efficiency.
