Can I load .mat files in a loop?

Hi,

I have 10 files namely img120.mat, img121.mat, img122.mat, img123.mat, img124.mat, img125.mat, img126.mat, img127.mat, img128.mat, img129.mat. RGB values saved in each .mat file.

I would like to load each .mat file, then imshow(RGB) to look at each image. Would it be possible to load all the .mat files in a loop rather than do load img120.mat, imshow(RGB), followed by load 121.mat, imshow(RGB), and so on and so forth...

Answer 1

[Matt J]

 filenames={'img120','img121',...};

 for i=1:numel(filenames)

    S=load(filenames{i});

     imshow(S.RGB)

 end

Another way:

filenumbers = 120:129; % <-- or whatever number range you want
for k=filenumbers
    S = load(['img' num2str(k)]);
    imshow(S.RGB)
end
