General

This file is based on the Curve Intersect function by Duane Hanselman. It extends the scope of the function to handle arbitrary lines / polygons, which may also have vertical segments or segments with non-increasing x-values.

Description
Calculate the intersection points of two 2D-lines / polygons.

Usage
[X,Y]=CURVEINTERSECT(H1,H2) or [X,Y]=CURVEINTERSECT([H1 H2]) or
[X,Y]=CURVEINTERSECT(X1,Y1,X2,Y2) or
-> (H1,H2) handles to line objects
-> (Xi,Yi) coordinates of lines
-> (X,Y) coordinates of intersection

Example
x1=rand(10,1); y1=rand(10,1); x2=rand(10,1); y2=rand(10,1);
[x,y]=curveintersect(x1,y1,x2,y2);
plot(x1,y1,'k',x2,y2,'b',x,y,'ro')
