利用matlab的gui设计的带有输入和输出功能的界面图形，实现等距线可视性很强，自己独立编写的数据和图形，学习非常值得,实现svm压缩图像，c语言(Using GUI of MATLAB to design interface graphics with input and output functions, realizing the visibility of isometric line is very strong, the data and graphics written independently by oneself are very worthwhile to learn, realizing SVM compressed image, C language)

Quadrature amplitude modulation generation.

说明：  salam. this file is about cryptography.

Artifical neural network forecasting. The code helps so much in training and testing data. It also developed in order to predict another new data base on the observed data

MATLAB code describing adaptive filter
