The ICP algorithm takes two point clouds as an input and return the rigid transformation (rotation matrix R and translation vector T), that best aligns the point clouds.

Example:
[R,T] = icp(q,p,10);

Aligns the points of p to the points q with 10 iterations of the algorithm.
The transformation is then applied using
R*p + repmat(T,1,length(p));

The file has implemented both point to point and point to plane as well as a couple of other features such as extrapolation, weighting functions, edge point rejection, etc.
