It is known that there is no sufficient Matlab program about neuro-fuzzy classifiers. Generally, ANFIS is used as classifier. ANFIS is a function approximator program. But, the usage of ANFIS for classifications is unfavorable. For example, there are three classes, and labeled as 1, 2 and 3. The...

This function calculates the principal curvature directions and values of a triangulated mesh. The function first rotates the data so the normal of the current vertex becomes [-1 0 0], so we can describe the data by XY instead of XYZ. Secondly it fits a least-squares quadratic patch to the local...

The main advantages of the Hausdorff regression are that one should not specify the direction of the errors (vertical, horizontal, orthogonal ... with the ordinary least squares) and that it is less sensitive with respect to the square of the distance.This is the original idea. Any contribution...
