Abstract
On an evaluation function consisting the square harmony of distance from many points of a linear manifold that passed a certain point, a general local flat or peak condition concerning the passing point and the projection source for work to the manifold was obtained. Next, conditions of requesting the inclination and the cut of the straight line to separate data in two dimensional feature plane is concretely led. The method of the use of the maximum square solution for a car model clustering was described in this manuscript, and an example of the numerical value was shown.
