matlab-forPID

用matlab实现的一个最小二乘法的简单例子(Using matlab to achieve a simple example of least squares)

说明：  一些用matlab编制的软件转化程序，如mst转换到sap中(compiled using the Matlab software conversion programs, such as Mst switch to sap China)

移动衰落信道，该书是英文版，非常好的一本书，还有matlab源代码。(Mobile fading channel, the book is the English version, a very good book, there are matlab source code.)

matlab宝典，编程使用，可以有效提高程度得效率(matlab，improve the code )

很好用的，生成归零码的程序，速度快， (R-Z code )

说明：  function [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 计算信号的循环谱 [Sx,f,alpha] = Sa(s,fs,M,N,read_f,del_f) 输入： s 序列 fs 采用频率 M 滑动频率窗长 N fft计算点数 read_f 可视频率（一般为载频的整数倍） del_f 可视频率间隔 输出： Sx 信号的循环谱 f 频率轴 alpha 循环频率轴(Cyclosationary Spectrum)
