Catenary - hanging rope between two points
Given two points in the vertical plane and a given length of rope, the supplied function computes the trajectory of the catenary between those points. Run plot_catenary.m for an interactive demo.
See
http://en.wikipedia.org/wiki/Catenary
for a full description of the catenary curve.

Hi Yuval,
Nice work!
However, there seems to be a problem with larger coordinates:
This works fine:
[x y]=catenary([-30 0],[30 0],100,20);
figure()
plot(x,y)
This doesn't:
[x y]=catenary([-300 0],[300 0],1000,20);
figure()
plot(x,y)
Not sure where the threshold is or what the bug could be.
Best, Hendrik
