This Matlab code shows how to perform edge detection by Sobel method in horizontal & vertical direction and the effect of increasing and decreasing the threshold value . Besides, you can try to perform the edge detection by other method in the same ways such as Prewitt , Roberts , Canny and others.

清华大学张旭东老师的《现在信号处理》第一次大作业的代码，题目多年未变，代码正确高效。(This code is programed for for the first project for modern signal processing ,which is tought by Zhang Xudong in Qinghua University.)

好多计算程序，可用于分析和计算！如：小波分析、时间序列等！(calculating program, eg:wavelet analysis)

说明：  为Matlab的日历显示加上农历信息。 (There is a command named "calendar" in MATLAB for get calendar infomation. This code improve the calendar information with the lunar.)
