Hello all.. I have problem to read my .txt file. I already convert my image to .txt file. My image size is 100x100. How to read it and use it in for loop ? here is my coding to change to image to .txt file.
a = imread('img2.jpg');
b = imresize(a,[100,100])
dlmwrite('test4.txt', b, 'delimiter', ',');
d = dlmread('test4.txt');
[x,y] = size(d);
i want to make comparison between two .txt file.That is why i need to read the .txt file.

You probably should first have a look at your .txt file to check if is has reasonable values, all separated by commas (or blanks, other delimiters may alos work)
type test4.txt
If this is ok, you can read the files using
T1 = dlmread('testimage.txt');
T2 = dlmread('anotherimage.txt')
and compute the difference image (no need to use for-loops)
D = T1 - T2;
and find the nonzero entries
ind_nonzero = find(D~=0);
