Abstract

This article concerns with an improved interpolation method based on Newton scheme with high dimensional data. It obtains the interpolation function when the nodes are arranged in a spatial grid. The spatial interpolation method is systematic and very useful in engineering field. As an example of application, we use the method to simulate the 3-D temperature field nearby a motor by 27 nodal temperature values. The results show that the interpolation function is quickly obtained within a limited cube space which realized data visualization. This demonstrates the effectiveness of the proposed method.
