You need to clarify your question. Perhaps you can give a specific example of what you want to do.

Do you mean in cardiology?

A New Efficient Method for Detecting Phase Singularity in Cardiac Fibrillation
Background

The point of phase singularity (PS) is considered to represent a spiral wave core or a rotor in cardiac fibrillation. Computational efficiency is important for detection of PS in clinical electrophysiology. We developed a novel algorithm for highly efficient and robust detection of PS.

Methods

In contrast to the conventional method, which calculates PS based on the line integral of the phase around a PS point equal to ±2π (the Iyer-Gray method), the proposed algorithm (the location-centric method) looks for the phase discontinuity point at which PS actually occurs. We tested the efficiency and robustness of these two methods in a two-dimensional mathematical model of atrial fibrillation (AF), with and without remodeling of ionic currents.

BTW, it looks like he's been spamming lots of math forums with this question, and has not been responding since posting the original question. We'll see if he comes back again... :confused:

Perhaps we should just close this thread explaining that C++ doesn't have a heart and hence can't have any phase singularities unless the Wizard of Oz intervenes.

@Stephen Tashi hit the nail on the head:
Perhaps you can give a specific example of what you want to do.
Just knowing that you are referring to optical phase singularities doesn't give us much to go on to give you advice on writing a C++ program to implement this stuff. What precisely are you trying to implement?

Why not contact the paper authors and ask about the software used. Its likely Matlab though.
