matlab，把文件解压后放入matlab的默认文件夹里，一般是（C:\MATLAB7\work）。在matlab主窗口中输入命令ima=imread( C:\MATLAB7\work\1.jpg )，然后输入命令[P,U,iter]=GPAS2(ima,2)，即可。绝对好运行-matlab, matlab to unzip the files into the default folder, usually (C: \ MATLAB7 \ work). In the matlab main window, type the command ima = imread (' C: \ MATLAB7 \ work \ 1.jpg' ), and then enter the command [P, U, iter] = GPAS2 (ima, 2), can. Definitely a good run
