用matlab来制作卫星绕地球做周期运动的动画，改变卫星的角速度的初值，可以画出圆形，椭圆形，逃逸轨迹。(Using matlab to produce satellites orbiting the earth to do periodic motion animation, change the initial angular velocity of the satellite, you can draw round, oval, escape trajectory.)

说明：  混沌工具function [dlogCr,dlogr,dlogCrCI]=vr(logCr,logr,alpha)(function [dlogCr,dlogr,dlogCrCI]=vr(logCr,logr,alpha))

用于海洋_气象研究的matlab工具箱,内有matlab代码，算例结果展示图片(matlab tool box for ocean and meteorology study.)

This histogram is a graph showing the number of pixels in an image at each different intensity value found in that image For an 8 bit grayscale image there are 256 different possible intensities , and so the histogram will graphically displays 256 numbers showing the distribution of pixels amongst these grayscale values
