基于matlab的画出一个不完整的椭圆，结果完美。只要稍作修改可以出来任意要求范围的不完整椭圆。(Matlab to draw the ellipse )

用径向基神经网络和BP网络预测的源码，径向基神经网络优于BP网络预测。(With RBF neural network and BP network prediction source, RBF neural network is better than BP network prediction.)

Proportional-Integral-Derivative (PID) control is the most common control algorithm used in industry and has been universally accepted in industrial control. The popularity of PID controllers can be attributed partly to their robust performance in a wide range of operating conditions and partly to their functional simplicity, which allows engineers to operate them in a simple, straightforward manner (exp. ref:national instruments). This file analyse different conditions and methods for tuning the PID controllers.
