For completeness, here is a straightforward Mathematica translation of the code used within MATLAB: phase[vec_?VectorQ] := Module[{n = Length[vec], ph = Arg[vec], df}, df = Differences[ph]; Do[ph -= 2 Pi Sign[df[[k]]] PadRight[ConstantArray[0, k], n, 1], {k, Flatten[Position[Abs[df], _?(# > Pi &)]]}]; ph]

Indeed, very useful. I wonder how to implement similar thing for Plot3D. It'd be needed for example when solving a Schrodinger equation and plotting Arg of wave-function versus time and space.
