Abstract
Some pulse-measurement applications, such as pulse-shaping, require rapid computation of the intensity and phase. Unfortunately, as discussed in Chapter 8, the generalized projections algorithm can take a few seconds to converge or longer for very large arrays. This is largely due to the minimization step that’s required in the standard formulation of generalized projections.
