介绍了常见的时频分析方法，包括短时傅里叶变换，Wigner-Ville分布以及小波变换等，结合MATLAB，引导读者如何运用其来进行时频分析(Describes the common time-frequency analysis methods, including short time Fourier transform, Wigner-Ville distribution and wavelet transform, combined with MATLAB, to guide the reader how to use it to carry out time-frequency analysis)

VC++与Matlab混合编程的快速实现，适合vc与matlab混合编程的学习者 很有用(VC++ With Matlab programming rapid mixing for vc mixed with matlab programming learners useful)

耳蜗实质上相当于一个滤波器组，耳蜗的滤波作用是在对数频率尺度上进行的，在1000HZ下，人耳的感知能力与频率成线性关系；而在1000HZ以上，人耳的感知能力与频率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(Cochlear substantially equivalent to a filter set, cochlear filter is used on logarithm frequency scale, under the 1000 hz, the perception of the human ear and a linear relationship with frequency In more than 1000 hz, the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula )

introductory look at what type of vibrations we might be dealing with when attempting to harvest ambient kinetic energy. The simplest type of vibration that could possibly occur, would be with a harmonic one, with a single frequency component at a constant frequency that does not change significantly in time.

非常有用的学习资料，用它学习matlab，从入门到精通，面面俱到(Very useful learning materials, use it to learn matlab, from entry to the master, everything)

cvlib_mex为封装了openCV重要函数的库，matlab可以直接调用文件从而运行openCV函数。压缩包中已包含cvlib_mex.mexw64文件，可以直接使用。PS:mexw64适用于windows下的64位matlab。(cvlib_mex important function to encapsulate the openCV library, archive already contains cvlib_mex.mexw64 files can be used directly. PS: mexw64 applicable under windows 64 matlab.)
