I have a closed curve in 2-dimensions, defined by C = [x y] (not generated from a function, but from data) and a vector with pt1 (the origin, also the centre of the closed curve) and pt2. How can I find the intersection between the vector and the curve?

Thanks,

Vic

Take a look at Fast and Robust Curve Intersections:

from the MATLAB FEX.

(There are lots of other ones there too. Do a search on intersect.)
