一种新的时频分析方法对应的程序送给搞EMD或者HHT但没有下载到完整程序的朋友。源码(A new time-frequency analysis method to the corresponding procedures for engaging in EMD or HHT but not downloaded to complete the procedures friends. Source)

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 )

说明：  两个信号的经典MUSIC方法DOA估计，性能良好(MUSIC classic two-signal method of DOA estimation, the performance of good)

Low pass filter desinged using matlab

一个基于神经网络的手写体数字识别的matlab程序，可以自行进行神经网络训练并识别给出相应的结果(A neural network-based handwritten numeral recognition matlab program, the neural network can be trained to identify themselves and give the corresponding results)

说明：  用于数据集的过采样处理，其中含有一个实例，可以参考。(Oversampling Processing for Data Sets,and it have a sample for study.)

说明：  初学微分方程数值解很实用的书籍，例子很详细，并附有程序。(Good book for student who wants to study tne numerical solution of differential equations)

说明：  序列x（n）的功率谱估计用matlab来实现(sequence x (n) of the power spectrum is estimated to achieve using Matlab)
