Now I have two surfaces. Both of them are extracted from 2 solid 3D objects which are generated by trangular mesh. (Note it's a triangular mesh not the rectangular one.) Now I want to find the intersection between the two object? If that cannot be down, then a simpler question: can I know if they intersect? (Not see from a graph, but use an algorithm to automatic determine if the two surface intersect). The data of the two shape is stored in samp_2.mat and tip_2.mat. In the two file, the data is stored in a respective matrix, where each row corresponds to the coordinate of a node on the object.

Can you attach your data? Did you try contour()?

contour() is a plotting tool, I want an algorithm that can automatic determine if the two shape is intersecting with each other or not. For the data, I have attatched it.
