Hi all, I'm trying to sort lists of random complex points on the unit circle using their angles as criterion to sort them: I mean, if z=Cos[a]+I*Sin[a] and w=Cos[b]+I*Sin[b]( 0<=a,b<2*Pi ), I want z<w if a<b; how can i do that? I tried to define Angle[z] as a piecewise funztion, but I still don't understand how to use it with Sort... Thanks, andrea
