Help with my period of my square wave

Hey Everyone, I dont know how to incorporate the period length into my square wave. I dont think that i have is correct. Any help?

         To = str2double(handles.Period) 
         Wo = (2*pi/To);
         N = str2double(handles.Coefs)
         Num = str2double(handles.PeriodAmount)
         R = (100*str2double(handles.Ratio))  %On/Off Ratio

        Snum = Num;
        Snum = Snum*2*pi;
        q = 0:.001:(Wo);
        y = square(Snum*q,R);
        plot(q,y);
        hold on;
        axis([0 Wo -1.5 1.5]);

Maybe try using repmat() instead.
