一个用matlab编的可以动的飞机动画制作小程序（源程序在网上下载，经本人稍加改动），注意六个状态值是需要外部输入的，比较适合做飞行器仿真试验用。(a series of the aircraft can move small animation (downloaded from the Internet source, I is modified), to six state value is a need for external input, more suitable for aircraft simulation experiment.)

kummer function for matlab

利用mathematicaplot 三维动态混沌分形图(Chaotic fractal graph and bifurcation diagram)

说明：  较为简单的均匀圆阵的方向图，可以用于实验仿真，波束成形等(The simple pattern of uniform circular array can be used for experiment simulation, beamforming, etc)
