matlab 编写的画图程序，用来画电阻率曲线的代码。(matlab prepared Paint program, used to draw resistivity curve code.)

The Kalman filter is a mathematical power tool that is playing an increasingly important role in computer graphics as we include sensing of the real world in our systems. The good news is you don’t have to be a mathematical genius to understand and effectively use Kalman filters. This tutorial is designed to provide developers of graphical systems with a basic understanding of this important mathematical tool.
