I have an 2 images of dimensions 211 x 322. of rgb image . i want to know how to use for loop. i have 2 variables i and j . i want to write for loop such that i has to be 1 while the j has to be looped 322 times. then i should go to 2 and loop of j should to be repeated 322 such that i should go to up to i for 211 times and j for 322 times.and finally i should able to store the values of each in an array and display the image.

You're describing two nested loops, but you haven't said what you want to do in the loops. You just say "store the values". What values?

In all likelihood, you don't need the loops at all.

在 MATLAB Online 中打开

You can convert rgb image to array.

path="https://pbs.twimg.com/profile_images/883859744498176000/pjEHfbdn_400x400.jpg";
% That image 400x400x3
matrixImage=imread(path);
imshow(matrixImage)
dimensions=size(matrixImage);
array=zeros(1,(dimensions*dimensions'));
indexarray=1;
for i=1:dimensions(1)
    for j=1:dimensions(2)
        for k=1:dimensions(3)
            array(indexarray)=matrixImage(i,j,k);
            indexarray=indexarray+1;
        end
    end
end
