lms算法，下载后自己运行即可，很方便的。我也是刚开始学(lms algorithm, you can download to run their own, very convenient. I am also just beginning to learn)

说明：  子波模拟的程序，对于用信号处理方法处理勘探地震信号的同学们有一些帮助(Sub-wave simulation of the process, with the signal processing method for exploration seismic signal processing students have some help)

图形用户界面（Graphical User Interfaces ，GUI）则是由窗口、光标、按键、菜单、文字说明等对象（Objects）构成的一个用户界面。用户通过一定的方法（如鼠标或键盘）选择、激活这些图形对象，使计算机产生某种动作或变化，比如实现计算、绘图等。(matlab gui)

主要用于地震数据处理中读取segy文件数据，也可以自己合成的数据保存为segy文件。(Mainly used in seismic data processing to read segy file data, you can also save their synthetic data for segy file.)
