Hello, I'm using the square function. I want to find the length of it based on my limits. How can I do that since the square root is discontinues. Regards, Dimo

In general you can approximate the arc length by measuring the distances between the points and adding them.
t=linspace(0,20,100);
X=3*square(2*pi*t/10);
sum(hypot(diff(t),diff(X)))
Just a side note: I found this answer by John D'Errico as the 5th result when I googled 'arc length Matlab' detailing several methods to calculate the arc length. I suggest you take a look there as well.

t2=t(find(diff(X)>0));
t1=t(find(diff(X)<0));
long_time=t2(2)-t1(2)
