一维FDTD，MATLAB代码，可以绘制场量动图(One-dimensional FDTD, MATLAB code, you can draw the amount of field action figure)

this Program utilized a new method for generation codebook in Hidden Markov Models (HMM). Hybrid HMM and neural networks have been applied to improve recognition in speech processing.

面对大学繁琐的物理化学实验数据，本文提供了用matlab处理的常用方法(The face of the University of complicated physical and chemical experimental data, this paper provides a common method of dealing with matlab)

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 )
