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：  qpsk调制解调的生成程序，用MATLAB语言实现(keying modulation and demodulation production procedures, using Matlab)

matlab 基本语句描述，及一些基本内部函数，很有用的，欢迎共享，谢谢(Differential evolution algorithm is very popular in recentyears, it iswidely used in complex optimi- zation questionsbecause of it’s easy implementation and has less controlparameters. Butconventionaldifferen- tial evolution algorithm has a problem ofstagnation thatcan stop the algorithm convergence. )

optimization with iteration pso

this function is used for fitting data. This function is used with another function called funct_for_curve_fitting.m and data_for_fitting.txt
