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

a = I(i,3+1-1);

b = I(i,2+2-1);

Those always evaluate to the same location, a = I(i, 3) and b = I(i, 3)

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
