基于MATLAB的语音识别MFCC特征提取算法(MATLAB-based speech recognition MFCC feature extraction algorithm)

说明：  实现HDB3编码，HDB3码是AMI码的一种改进型，其目的是为保持AMI码的优点而克服其缺点，使连“0”个数不超过3个。(Achieve HDB3 encoding, HDB3 code is a modified AMI code, its purpose is to maintain the benefits of AMI code to overcome its shortcomings, so that even the &quot 0&quot the number of not more than 3.)

These codes are very useful in the simulation of HAP

delta sigma AD转换模型的matlab工具箱，包含调制，滤波，计算信噪比等多多方面内容，非常全面。用之进行相关研究，事半功倍。(delta sigma is the AD conversion models matlab toolbox, including modulation, filtering, calculation of signal to noise ratio, etc. a lot of aspects, very comprehensive. Used more efficiently.)

Horn_Schunck_Optical_Flow_Method，值得学习(Horn_Schunck_Optical_Flow_Method, worth learning)

emd算法，详细英文注释，程序能现实IMF各次图形(emd algorithm, in English, can realistically IMF various graphics)

自己编写的Matlab源码，主要采用时域有限差分(FDTD)法实现色散介质的电磁仿真。(I have written Matlab source, the main use of finite difference time domain (FDTD) method to achieve the electromagnetic simulation of dispersive media.)

这个程序是拿来计算像差的，输入相关变量，运行就能计算出像差的值(This program is used to calculate the aberrations, enter the relevant variables, running can calculate the value of the aberration)
