How to make a variable be greater than and less than two numbers

I have code that I'm working on where the variable t needs to be greater than or equal to zero and also be less than or equal to 2pi. How would I code that into matlab?

Have this code to alert the user if the value of t is out of range:

if (t < 0) || (t > 2*pi)
    errorMessage = sprintf('t needs to be between 0 and 2*pi, inclusive.\nYour t of %f is out of range.', t);
    uiwait(errordlg(errorMessage));
    return; % Quit since the value can't be used.
end

Im sorry. Its a class for college and we haven't begun using if statements. I need to set it as a variable for an equation later in the code.

I just realized the answer was much simpler. It would just be t = linspace(0,2*pi); . So sorry for wasting your time
