matlab 基础教程，第三章，适合初学者(matlab Essentials, Chapter III, suitable for beginners)

The purpose of this document is to give a medium-length introduction to the essentials of MATLAB and how to use it well. I’m aiming for a document that’s somewhere between a two- page introduction for a numerical methods course and the excellent but longer Getting Started and other user guides found in the online docs. I use it in a week-long “boot camp” for graduate students at the University of Delaware in the summer after their fi rst year of study.

Efficient Kmeans using Multiple Threads

采用自相关函数法求基音周期，将采样得到的声音信号按每20ms一帧分为若干帧，并对每帧的序列求自相关函数，取自相关函数第一个最大值点算出基音周期，并以帧为横坐标，基音周期为纵坐标画图，并去除野点，最后取图中浊音部分即面积较大部分的值作为基音周期。(Using the autocorrelation function method pitch period, the sound signal is sampled every 20ms frame is divided into a plurality of frames, and each frame sequence uates the autocorrelation function, taken the first maximum point of correlation function calculated the pitch period, and frame as the horizontal, the vertical axis pitch drawing and remove outliers, and finally take the value of the area that is part of a larger portion of the figure as voiced pitch.)

用PDA 概率数据关联算法跟踪多目标.MATLAB 在二维平面跟踪多个目标。(Track Multi-target with PDA)

基于DQPSK差分编码调制解调,希望对你有帮助。(DQPSK modulation and demodulation based on differential encoding, I hope to help you.)

说明：  用FCM算法实现了图像分割，效果较好，可以更改聚类数目(FCM algorithm is used to realize image segmentation. The result is good, and the number of clusters can be changed)

code is matlab which is thrshold code

说明：  对彩色图像进行K均值的图像分割，可用于模式识别(K on the mean color image segmentation, can be used for pattern recognition)
