I have tried to run this code many times , even changed the equation , values but i am not able to get the correct answer , here A given is before its transpose of glcm
% Convert to grayscale if necessary
%if size(img, 3) > 1
%img = rgb2gray(img);
%end
I = [0 0 1 1;
0 0 1 1;
0 2 2 2;
2 2 3 3];
A = [2 2 1 0;
0 2 0 0;
0 0 3 1;
0 0 0 1];
D = A';
E = A + D;
E
%glcms = graycomatrix(I);
%glcms
m = 5;
%n = 4;
count = 0;
%count1 = 0;
n = 3;
o = 4;
for i = 1 : 4
for j = 1:4
for l = 1 : 4
for k = 1 : 4
x = I(i,1);
y = I(i,3-1);
a = I(i,3+1-1);
b = I(i,2+2-1);
if (I(i,j) && I(i,n-j)) == (I(i,n-k) && I(i, n+1-k))
%disp('Entered the control');
% count = count+ 1;
%end
end
end
B(i,j) = count;
end
%B(i,j) = count;
%end
%end
end
%if (E == B)
% disp('Correct Answer');
%else
% disp('Not Correct Answer');
%end

E==B is going to do an element-wise comparison, returning a matrix the same size as E and B with logicals (0's, 1's) where the elements in the same positions are equal, sounds like you want a simple true/false if E and B are the same
if you're wanting to build a condition on the entire matrices being equivalent, then you probably want to use:
if isequal(E,B)
...
end
isequal() will output a single true/false value
you could also use all(all(E==B)) to reduce the element-wise comparison to a single true/false

you're very welcome...the latest version is much easier to follow too, nice structure and commeting as well, bravo!
