请教，matlab function---image

来源: cat&spider 于 2008-01-22 18:41:57 [] [旧帖] [给我悄悄话] 阅读数 : (279 bytes)

A=[1,1
2,10];
image (A);
caxis ([0,10]);
colorbar;

请教，why caxis does not work here (it works if I use pcolor, or mesh, but not for image only)? if I would like to define the max and min of the colorbar here, what matlab function should I use?

Thanks.

• image的颜色是由colormap决定的，用RGB真彩就简单点。 -what124- ♂ 给 what124 发送悄悄话 (311 bytes) () 01/23/2008 postreply 08:11:38
