how to use this symbol in matlab?? ±

I have a if loop where i need to check the condition.The loop is something like this:

if(tht(1)==thf(1))

      S='Orginal Note';  
  disp(S);

else

          S = 'Fake Note';  
         disp(S);

end

Inside that if loop i want to place that ±. How can i do this?? For example like:

if(tht(10)==thf(10±5))

How it can be done??

Did you mean a simple test for two different values?

if( tht(10)==thf(10-5) || tht(10)==thf(10+5) )

Cant it be used in just one situation both together.

If you are asking if ± is an allowed operator in MATLAB, the answer is no.
