square[x_] := 1 - 2*Floor[Mod[x, 2]] Ingolf Dahl, Chalmers University -----Original Message----- From: Peter Dimitriou [mailto:peterangelo at mindspring.com] To: mathgroup at smc.vnet.net Subject: [mg31680] [mg31663] square wave function To all who responded last time I posted, thank you, I was able to resolve that on my own. My new Question deals with the following lines of Mathematica code: Clear[square] square[x_] := 1 /; 0<x<1 square[x_] := -1 /; -1<x<0 Plot[square[x], {x,-1,1}] This defines and plots a square wave of period 2 between -1 and 1. The question is how do I define this for all x (-inf<x<inf, with period 2) in Mathematica? The Only hint I get is to consider using the Mod function. Scratched my head long enough anyone out there willing to help? Peter
