Adds a warning to a plotting function that when the amplitude of a complex number is zero, then the phase will not be recovered correctly. This will cause the images to look discontinuous because zero amplitudes will render as having phase of PI or zero.
Purpose
Adds a warning to a plotting function that when the amplitude of a complex number is zero, then the phase will not be recovered correctly. This will cause the images to look discontinuous because zero amplitudes will render as having phase of PI or zero.
