synopsis on speaker recognition

说明：  渐开线标准直齿圆柱齿轮，齿数z=35, 模数=5，计算渐开线齿轮参数并绘制渐开线齿轮(Draw cylindrical involute gear , teeth equal to 35, module equal to 5, calculate parameter of involute spur gear and draw the gear)

ofdm系统基于matlab的m语言仿真(OFDM system is based on the m language matlab simulation)

MATLAB 的学习的例子，一些很常用的学习资料(There are some nice matlab learning examples which may be your usful study materials.)

代码实现了对刀具图像的预处理。并且有完整的word文档进行讲解(image preprocessing.)

This script shows the difference of using zero padding (GI) in the end of OFDM symbol and using cyclic prefix (CP).

MFCC program,is written by my son,you can use it very simply!

说明：  排列熵算法是一种动力学突变检测方法，能够方便、准确的定位系统发生突变的时刻，并且对于信号的微小变化具有放大作用(Permutation entropy algorithm is a dynamic mutation detection method, which can easily and accurately locate the moment of system mutation and amplify the small change of signal)

交通流研究中的元胞自动机模型源码，可以模拟交通现象(traffic flow study of Cellular Automata Model source, the phenomenon can be simulated traffic)
