a e
1 1
1 2
3 2
3 2
The above is my input table. Check 'a' for the value '1'. The corresponding 'e' value differs. So, we should not consider it. Check 'a' the value of '3'. The corresponding 'e' values are same. How to develop code for this?

Then see my answer. Also, what does "class(a)" show when you issue that command? If you want to make absolutely sure a and e are integers, wrap them in an int32() when you create them.

AE = [a e]; %The initial array
out = AE(abs(diff(AE,1,2)) < eps(100),:);

I think you should consider using isequal() . The function works with single, double, string.

If they're integers, use ==, like
if a == e
if they're floating point, you need to check against a tolerance:
if abs(a-e) < 0.0001
