matlab入门的一些知识，希望对大家能有所帮助。(Some knowledge of matlab start, hope we can help.)

The best book I have been seeing for Sound and using digital signal processing

语音识别MFCC特征提取matlab代码。 「梅尔倒频谱系数」（Mel-scale Frequency Cepstral Coefficients，简称MFCC），是最常用到的语音特征，此参数考虑到人耳对不同频率的感受程度，因此特别适合用在语音辨识。(Speech recognition MFCC feature extraction matlab code. Mel cepstrum coefficient (Mel- scale Frequency Cepstral Coefficients, MFCC), is the most commonly used to the phonetic characteristics of this parameter given ear to the feelings of different frequencies, so especially suitable for use in speech recognition)

本文为 Stephen J.Chapman《MATLAB 编程（第二版） 》英文影印版的中文译本，这本 书对初学者很好的入门教材。之前从网上下载到邢树军兄弟译的 pdf版本(MATLAB-from fresh to expert.MATLAB Programming for Engineers)

LTE-Advance信道预编码矩阵构造的matalb仿真程序，具有很好的使用价值。(LTE-Advance-channel pre-coding matrix simulation program constructed matalb has good value in use.)

it just show the different type of signals and their matlab codes

IAE方法检测过程的振荡。绝对积分误差方法。(IAE approach for oscillation detection)

夫琅禾费衍射的几个程序，有单缝衍射，多缝衍射，和矩孔的衍射。(Fraunhofer diffraction of several procedures, single-slit diffraction, multi-slit diffraction, diffraction and the moment the hole.)

数字基带系统传输，有完整的编码译码过程，高斯白噪声信道(Digital baseband transmission systems, a complete coding and decoding process, Gaussian white noise channel)

主成分分析法，其本质是实现高纬到低维的分析，用matlab实现的代码(Principal component analysis, by its very nature is to achieve the high latitudes to low-dimensional analysis, implemented with the matlab code)
