用MATLAB写的小程序，希望感兴趣的朋友可以看下。。(Write small programs using MATLAB, interested friends can look. .)

this is gradient magnitude code in matlab

读取txt文本文件中的数据，然后自动画滞回曲线图！可以区分不同周期，用不同颜色描述！(Txt text file to read the data, then the hysteresis curve from the animation! Can distinguish between different periods, with different color descriptions! )

本程序的目的是模拟一个ARMA模型，然后进行时频归并。考察归并前后模型的变化。(The purpose of this program is to simulate a ARMA model and then to merge time and frequency. The changes of the model before and after the merging were investigated.)

this program is for frquency shift keying

简单的表单程序，希望对广大同志们的学习有所帮助，谢谢大家。(biaodan)
