kd树的实现，用到matlab(kd tree realization used Matlab)

该Matlab算法，可以实现振动数据的文件的读取，进而可以进行时频分析，得到信号特征值(The Matlab algorithm can achieve vibration data of the document read, in turn, can be time-frequency analysis, Signal Characteristics)

傅立叶计算以及短时傅立叶计算、功率谱分析及各自图形(Fourier calculation and short-time Fourier, power spectrum analysis and their own graphics)

说明：  扑克识别代码，能识别扑克的数字和黑红梅方等颜色。(Poker identification code, to identify the number of poker and black color Hongmei Fang.)

本程序研究了在不同符号序列条件下，基本Gardner算法和一种修正Gardner算法的定时误差特性(This program studied the sequence of symbols in different conditions, the basic Gardner algorithm and a modified Gardner timing error characteristics of the algorithm)

实现matlab的figure图像嵌入到自己应用程序界面的功能，利用该方法也可以能够对于Figure图像进行个性化定义，能够使Matlab和自己的程序合为一体， 为基于matlab的可视化界面编程的混合编程有很大的借鉴意义。(Matlab implementation of the figure images embedded into their own application program interface features, using this method can also be able to personalize the image for Figure definition, able to Matlab and its own procedures for combined into one, matlab-based visual interface for programming mix programming a great learn. )

informax 程序，可以分离超高斯及亚高斯源，并且自带有六个源信号(informax program, you can separate super-Gaussian and sub-Gaussian source, and comes with six source signals)
