在 MATLAB Online 中打开

 [I map]=imread('kids.tif');
RGB = ind2rgb(I, map);
R   = RGB(:,:,1);
G   = RGB(:,:,2);
B   = RGB(:,:,3);

I did not get any result from these code.

Are you saying that you ran the code and MATLAB did not create any variables at all? You did not get results in the variables I, map, RGB, R, G, B? Try it this way:

workspace
clear all;
[I map]=imread('kids.tif');
RGB = ind2rgb(I, map);
R   = RGB(:,:,1);
G   = RGB(:,:,2);
B   = RGB(:,:,3);

Now, look at the workspace panel. Are any variables at all listed there? There should be.

Next, define what you mean as print. Do you mean to print numerical values, like 1, 43, 79, etc. Or do you mean that you want the image itself printed as an image?
