integral--PID-algorithm

模拟退火的实现，使用matlab实现的，可以直接运行(simulated annealing，Matlab)

这个程序是根据前推回代法计算潮流的，算法简单明了。(This program is based on forward and backward substitution method to calculate the trend of the algorithm is simple and clear.)

matlab上机实验：系统响应及系统稳定性(System response and system stability )

基于粒子群的多目标优化搜索算法，欢迎使用(Multi-objective optimization search algorithm based on PSO, Welcome)

本人自编的一个matlab程序，其功能是使图像的背景变为透明，并保存。(My an own matlab program, its function is to make the background in an image transparent, and save the new image.)

在不同信噪比条件下，对于不同调制方式所产生的误码率曲线！(Signal to noise ratio in different conditions, for different modulation generated BER curves!)

new k-means clustering

说明：  根据教科书上已经给出的简单的数学算式，运用matlab编写出简单的代码，计算出结果(According to the textbook has been given a simple mathematical formula, using matlab write simple code to calculate the results)

对确定的一个负反馈系统，进行稳定性判断、最小相位系统判断；求取零点、极点、放大系数；绘制阶跃响应图。(To determine a negative feedback system, judge, judge the stability of minimum phase system calculating the zeros, poles, amplifying coefficient drawing step response diagram.)

说明：  matlab代码读取O文件和N文件,计算GPS卫星位置，然后输出(matlab code ,read O file and N file，caculate GPS position and print out.)
