What is the problem in the for loop?

I've a problem in the for loop to extract texture features of images of a folder. The problem is in this line:

Im2=ComputeRankTransform(filename);

Can anyone please help me to access all images??

 clc;
Im1=ComputeRankTransform('bi4.jpg');
folder = fullfile('E:\4-2\Thesis_codes\texture\code\dependencies');
srcFiles = dir(fullfile(folder, '*.jpg')); 
for i = 1 : length(srcFiles)   
    % determins how many images are there in the folder,
  filename = fullfile(folder,srcFiles(i).name);
  thisImage = imread(filename);
    Im2=ComputeRankTransform(thisImage);
  sizeOfIm1=size(Im1);
    sizeOfIm2=size(Im2);
    if(sizeOfIm1==sizeOfIm2)
        if(Im1==Im2)
            fprintf('Yes\n');
       else
            fprintf('No\n');
        end
    else
        fprintf('No Dimension\n');
    end
end

That is hard to tell based on the information you provide. However, here are some links on debugging in Matlab

You can ask me any information you need:

My code is:

 clc;
Im1=ComputeRankTransform('bi4.jpg');
%Im2=ComputeRankTransform('bi9.jpg');
folder = fullfile('E:\4-2\Thesis_codes\texture\code\dependencies');
srcFiles = dir(fullfile(folder, '*.jpg')); 
loopCount=0;
srcFiles = dir(fullfile(folder, '*.jpg'));
for i = 1 : length(srcFiles)   
    fprintf('for loop %i',i);
    % determins how many images are there in the folder,
  filename = fullfile(folder,srcFiles(i).name);
    %filename
  thisImage = imread(filename);
    %a=size(thisImage);
    %a
    %Im2=ComputeRankTransform(thisImage);
    Im2=ComputeRankTransform(filename);
    Im2
    sizeOfIm1=size(Im1);
    sizeOfIm2=size(Im2);
    %sizeOfIm2
    sizeOfIm2
    sizeOfIm1
    if(sizeOfIm1==sizeOfIm2)
        if(Im1==Im2)
            fprintf('Yes\n');
       else
            fprintf('No\n');
        end
    else
        fprintf('No Dimension\n');
    end
    loopCount=loopCount+1;
end
loopCount

The function is:

 function RT = ComputeRankTransform(I);

    %Computes the rank transform of an image

    %Input:     I (one-channel image)
    %Output:    RT (rank transform

    [rows cols] = size(I);

    nPixels = rows*cols;

    I = reshape(I, 1, nPixels);
    [sorted, indices] = sort(I, 'descend');
    RT(indices(1:nPixels)) = 1:nPixels;
    RT = reshape(RT, rows, cols);

 end

The problem is we don't know what you mean when you say "help me to access all images" You say

thisImage = imread(filename);

so as far as we can tell, you're accessing the image right there with that line of code, and we don't know why you're asking.

By the way, you don't need to put useless tags (which I deleted) like "matlab" or "code" or similar on your post. All posts here are on MATLAB code.
