Programming: keep theta between specific values

Hi every one,
I have a problem in programming. I have theta which start from 0 and goes to unspecified value. I want to reset theta if it reached to 2pi and keep it always between [0,2pi]. I wrote a code but it is not true for all situation(Ex after 4pi). My code is:
if theta>2*pi
theta=theta-2*pi;
end

You can do that with the rem function:
x = linspace(0,10*pi);
theta = rem(x, 2*pi);
figure(1)
plot(x/pi,theta/pi)
grid
xlabel('Angle (x \pi)')
ylabel('Angle (x \pi)')
They are plotted as multiples of pi for convenience in visualising the result.

A (1x1) matrix is a scalar.
My code does exactly what you illustrated. It produces vectors of values from (0,2*pi) from your linearly increasing vector that goes from zero to at least 6*pi.
