First,a formula to calculate the normal vector of any hyperplane is given and a mixing matrix recovery algorithm based on the normal vector of any hyperplane is proposed.

This paper presents a new way to rotate the normal vector of the plane.

According to the characteristic of the wave field data, a simple algorithm is used to calculate the normal vector at the nodes.

The Median Theorem will be applied to determining the normal vector of the point on parabola and then using the technology of tip compensation to measure the parabola accurately.

In this paper, first introduces about normal vector and then deals with how the stylus regulating automatically its own level on contact complex surface and holds constant level with nominal deflection.

Our method uses object surface normal vectors to obtain vector distances between 3D objects.
