If your data always has V form (look like triangle). Tree corners can be found. Find farthest corners using pdist2()
Divide points into 2 groups. If distance point-corner smaller than radius:
Use polyfit() to calculate coeffiecients of line. What if angle between calculated lines is not 90 degree?

What I would try first is to use principal components analysis ("PCA") to identify the two axes. Use pca() if you have the stats toolbox. Then you can fit lines with polyfit() going through the points along each PC. Use the points at the limits to determine where the lines start and stop. Sorry, no I don't have code that does this already - I'd have to develop it just as you would.
Another method you might also try is RANSAC.
