Strange, as this passes all of the tests on my box. (How did I pass a random test, and fail the hard coded ones?!?) Maybe a bsxfun issue?
Rounding errors of sqrt. Possible fix circle(3)+10*eps(circle(3)) and r+10*eps(r)
Better, but still not quite there. With those fixes, it passes everything but test 2. I'll try a couple more changes, and then just throw in a hard coded hack for case 2. (Or maybe I'll just ask Tim for his solution. :-)
Another astounding solution by Tim using complex numbers and for loops that create vectors. Example of for loop vectorization: for i=nchoosek(3:6,2)',i,end. Very nice mthod.
