matlab发送消息的代码，包括m文件和c文件

通过独立分量分析，来实现盲源信号的分离。程序简单易懂，适合初学者(Done by independent component analysis and blind source separation of signals. Program is easy to understand, suitable for beginners )

主成分分析程序，简单易懂，修改路径可直接运行，附带详细说明(The PCA program with detailed explanations is very useful and effective，easy to understand. It can be run after modifying the input path.)

高阶累积量，用于信号的调制识别，性能较好(high order cumulant,used to AMC.)

根据像素点进行圆匹配。根据像素点进行圆匹配。(According to the pixel round match. According to the pixel round match.)

说明：  To find the encryption and decryption of image which is affected by the noise.

EMD或者LMD的能量密度与其平均周期的乘积K值，当K值发生较大变化的时候，证实该分量为白噪声，可以剔除，将剩下的分量进行重构，达到去噪的目的。(The product of K EMD or LMD energy density and average cycle value when the K value was changed greatly, the component for white noise can be eliminated, the remaining components are reconstructed to achieve the purpose of de-noising.)

利用MATLAB进行数据拟合，常见的数据拟合方法。包括：一元函数插值、样条插值、多项式插值或拟合 、曲线拟合、拉格朗日插值法等。(MATLAB data fitting, common data fitting methods. It includes: interpolation of unitary function, spline interpolation, polynomial interpolation or fitting, curve fitting, Lagrange interpolation, etc.)

说明：  用ELM模拟了指定数据的拟合效果，表明ELM特别适合本数据！(The fitting effect of the specified data was simulated with ELM, indicating that ELM is particularly suitable for this data!)
