\doxysubsection{Detailed Description}
Rotate an array pair representing the components of a vector. Rotation is applied across the first and second axes of the array. This rotation should be applied when the fields satisfy vector transformation rules. For example, the u and v components of a velocity will map from one to the other for quarter turns, with a sign change in one component. A half turn will map elements onto themselves with sign changes in both components.
