11 Feb 2014 Ray/box Intersection Ray/box intersection using Smits' algorithm. The zip file includes one example of intersection. Author: Jesús P. Mena-Chalco Zhu, X

This code doesn't work at all!
For the following example test case:
[flag, tmin] = rayBoxIntersection([0 0 0], [-1 -1 -1], [2 2 2],[4 4 4]);
It returned with a flag "1"!
The author should withdraw the code.

Would you please explain why the threshold 'tv' is computed in this way?. I mean why its value depends on the length of the DNA sequence? what is the logic behind this and if this way of calculating the threshold appears in any reference.
