自己编写的二维地震数据分析及显示，可以给二维勘探的同行们提供帮助(2Dseismic data analysis and plot)

说明：  matlab 时频分析工具箱 ，放在matlab下即可运行(Time-Frequency Analysis toolbox matlab)

Elman神经网络的数据预测—电力负荷预测模型研究(Elman neural network data prediction- Power Load Forecasting Model)

This program is testing the function

matlab中用梯度下降法进行线性回归，是机器学习的例程。很好很实用。(machine learning.linear regression and gradient descent way.)

to determine whether the code is uniquely decodable or not.

基于灰度梯度最大熵的分割方法，先通过聚类进行改进做初分割然后再进行细分割。(Segmentation of gray gradient based on maximum entropy, first through the clustering is improved. At first, then the fine segmentation segmentation.)

对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

说明：  basic histogram equalization

一种有效的降维方法的源代码，原始的，可以很方便的改进。(it is easy to understand, monifoid leaning)
