单频率成分的离散频谱校正源程序（能量重心校正法）。针对单一频率谐波信号的离散频谱校正，可选择加矩形窗和汉宁窗。已调试通过。(Matlab Codes for Ratio correction based on different window.Rectangle and Hanning Window can be choose to act.)

自己编写的EMD程序，三次样条插值也是自己编写的(I have written EMD program, cubic spline interpolation also write your own)

对图像进行离散余弦变化处理，了解余弦变化系数以及余弦变化后回复图像与原图的区别(After the change of image processing discrete cosine understand cosine cosine coefficient of variation and difference with the original image Reply)

2－d music算法是在一维music算法的基础上进行的一种算法，它是需要测的是方位角和俯仰角(Algorithm for 2-d music is music in the one-dimensional algorithm based on an algorithm, it is the need to measure the azimuth and pitch angle is)

单端反激式开关电源设计的matlab源码(Design Code of the Single-end Reverced Exciting Switching Power Source implemented by MATLAB.)

EM算法，是一种无监督的聚类算法，可以实现对数据的处理，对不同数据进行聚类，生成类内相似度最大(EM algorithm is an unsupervised clustering algorithm, the data processing can be achieved on different data clustering, to generate the maximum within-class similarity)

实现希尔伯特-黄变换的功能，并带有一段测试数据。希尔伯特-黄变换是使用EMD分解将信号分解为本征模态函数（IMF），然后求得IMF分量的瞬时频率。其对于非稳态和非线性信号具有优良的效果。(The function plot_hht is a realization of the Hilbert-Huang transform (HHT). The HHT decomposes a signal into intrinsic mode functions (or IMFs), and obtain the instantaneous frequency data. It is designed to work well for data that are nonstationary and nonlinear.)

This paper is based on artificial neural network. artifivial neural network is a patter recognition mechanism that resembles the human brain. It have input layers, hidden layers and output layers. ANN provides beter recognition accuracy than other classifiers.

使用BP算法实现语音识别及预测的功能，调试可用(BP algorithm to achieve the function of speech recognition and forecast)
