说明：  地统计学中基于空间变异原理的差值分析，做空间分析的好材料。matlab实现(To statistical theory based on spatial variability of the difference analysis, a good material to do spatial analysis. matlab implementation)

Run the program by typing DoublePendulumAnimation at the Matlab prompt. Make sure that your current directory in Matlab is set to the directory containing DoublePendulumAnimation.m. To run the animation with the default parameters, simply click the Begin button to start the animation. You can experiment by changing the parameters and initial conditions and hitting the Begin button to see the motion of the double pendulum. 1)If the animation goes too slowly decrease the number of points. 2)If the animation is too fast or jerky increase the number of points. 3)Vary the time span to either increase or decrease the length of the animation.

CHAPTER 10 控制系統的設計 許多受控程序的轉移函數包含一對或更多對的共軛複數極點。在s 平面中若複數 根非常接近虛數軸，則閉迴路系統會變成輕微阻尼或不穩定(CHAPTER 10 control system design of many controlled program transfer function contains a pair or more pairs of conjugate complex number of poles. If the plural in the s-plane root number very close to the imaginary axis, then the closed loop system becomes slightly damped or unstable)

说明：  研究智能算法的同学，可以参考这些例程学习(Students studying algorithms can refer to these routines)
