  This document describes an algorithm to scale a complex vector by the
reciprocal of a complex value. The algorithm computes the reciprocal of the
complex value and then scales the vector by the reciprocal. Some scaling may be
necessary due to this 2-step strategy, and the proposed algorithm takes scaling
into account. This algorithm is supposed to be faster than the naive approach
of dividing each entry of the vector by the complex value, without losing much
accuracy. It also serves as a single strategy for scaling vectors by the
reciprocal of a complex value, which improves the software maintainability.
