MATLAB: Remove the discontinuity from tan(x) where odd multiples of pi/2

discontinuityMATLABodd multiplespi/2tan(x)x

Hi i have the function;
f=tan(x)
where
x=linspace(-2pi,2pi,200)
I was wondering if you would know how to remove disconuity of the function which is odd multiples of pi/2.
I was thinking using the rem(x, 2) ==0 function and f(_) = NaN but i dont know how to structure it.
By the way it is for when i plot it, so there are no vertical lines (the disconuity which is all odd multiples of pi/2).

I suggest:
x=linspace(-2*pi,2*pi,200);
f=tan(x);
f(diff([0 f]) < 0) = NaN;
