这是我们上课用的Matlab课件，非常有用，希望对大家有用。。。(This is our school with the Matlab software, very useful, useful for all of us hope. . .)

1 录入一段语音，对其进行时域频域处理，通过变频、变速达到变声目的，且使处理后的语音信号不影响正常收听与理解。 2 用图形用户界面（GUI）对上述变声前变声后进行时域频域图形输出，不同的频率、速度有不同的输出，且对前后波形进行比较 (1 entry a voice, the frequency domain and time domain by frequency conversion variable speed, processing to make the treatment and voice purpose, after the speech signal shall not affect the normal to listen to and understand. 2 with the graphical user interface (GUI) voice of the above voice before after the frequency domain in the time domain graphics output, different frequency, speed have different output, and compared before and after waveform )

广义奇异值分解程序，常应用于数据处理，例如信号处理(The generalized singular value decomposition (GSVD) is a matrix decomposition more general than the singular value decomposition. It is used to study the conditioning and regularization of linear systems with respect to quadratic semi-norms.)

This code is about synthetics seismic data.

四元数matlab程序中的FFT计算程序，很好很强大的(Quaternion FFT matlab program calculation program, very good very strong)

matlab算法第11章内容其他部分陆续上传中请稍后(matlab algorithm for the content of other parts of Chapter 11 in succession, please upload later)

The recognition of noise as a source of annoyance began in antiquity, but therelationship, sometimes subtle, that may exist between noise and money seems to be a development of more recent times. For example, the manager of a large wind tunnel once told one of the authors that in the evening he liked to hear, from the back porch of his home, the steady hum of his machine 2 km away, for to him the hum meant money. However, to his neighbours it meant only annoyance and he eventually had to do without his evening pleasure.

利用MATLAB解决<偏微分方程数值算法>中的一些问题,如插值求解(Use MATLAB to solve <partial differential equations numerical algorithm> in a number of issues, such as interpolation to solve)

这是计算光子晶体程序，对研究光子晶体的同行很有用(This is the calculation procedures for photonic crystals, photonic crystals to study the usefulness of the peer)

MATLAB 自抗鞭策扰控制器仿真程序，采用S函数编成。(MATLAB simulation since anti-scrambling controller)
