x1s=im2double(x11(:,:,2));
x1i=im2double(x11(:,:,3));

area1=x1h>= 0/360;
area2=x1h<=60/360;
area=and(area1,area2);
c1=and(x1s>=40/255, x1s<80/255);
c2=and(x1i>=185/255, x1i<1);
c=and(c2,area);
subplot(221); imshow(x1); subplot(222); imshow(x1h);
subplot(223); imshow(area); subplot(224); imshow(c);

帮我看看这代码,最好每行后面都有注释.c=and(c2,area); 这行我运行不起来.帮我看看是不是出问题了.哪位大哥帮忙下.非常紧急啊.

% 程序我都给你加上注释了,我这边可以运行,没有问题,你那边是不是因为缺少什么工具函数导致的 ,图片是我这边的运行结果
