How would you like to quantify different and similar? That part is not a Matlab question, but a question for you.
You should also include some examples of how your variables look. There is no general metric for difference or similarity that works for all data types.

I am assuming you want to check whether two variables are equal or not. For that purpose you can use the 'isequal' function which returns logical 1 (true) if A and B are equivalent; otherwise, it returns logical 0 (false). Please refer the following code snippet on how to use it:
A = 0;
B = 0;
tf = isequal(A,B);
