关于空间计量模型的MATLAB程序

1280点fft变换，改变传统的需2046点FFT的情况。(1280 point FFT，radix 4 and radix 5 )

说明：  研究基于粒子群算法控制系统PID参数优化设计方法以及对PID控制的改进。( study the optimal design of PID parameter of the control system based on Particle Swarm Optimization and find a way to improve the PID control. )

This file includes demodulation algorithm who is using and studying the matlab simulink. I hope this zip file would be helpful for them.

这本Matlab编程是Stephen J. Chapman的经典作品，本上独特的强调自上而下的编程方法，而且在全书中皆有提醒和注意常犯的错误(This is Stephen J. Chapman Matlab programming classics, this emphasis on the unique top-down programming, but also in the book have the sound alerts and attention to common mistakes)

K-Means聚类算法 Matlab代码(K-Means clustering algorithm Matlab code)

用matlab仿真迫零算法。有两个文件，一个是迫零函数，一个是主程序。主程序调用迫零函数。(failed to translate)

基于X12的季节调整模型的matlab程序(X12 seasonal adjustment model based on matlab program)

说明：  UWB1000模块测试所得数据初步处理之后，已知锚点的坐标，可利用该文件里的程序解算标签三维位置。(After preliminary processing of data obtained from UWB1000 module test, the coordinates of anchor points are known, and the program in this file can be used to calculate the three-dimensional position of tags.)

用Matlab以及c语言求语音序列的倒谱 这某段语音信号求FFT、取模、取log、IFFT得到倒谱，并画图。选取一段进行分析，分别对浊音和清音各自求倒谱。(Using Matlab, as well as for c language serial Cepstral voice that voice signal for a certain period of FFT, check mode, check log, IFFT been cepstrum, and drawing. Select a section of the analysis, respectively, and the voiceless to voiced their demand cepstrum.)
