for loop not working

here is the for loop that im trying to run. my problem is the variable PON is not getting updated and assigned inside the for loop. Can someone please help?

% the size of VAL is 3*1. M=3. the issue is the value of PON is showing 0.
[M,N]=size(VAL);
PON=0;
for i=1:M
   if(i>i+1)
       PON=VAL(i+1); % when i execute this line seperately it works fine but when the whole code is executed the value of PON is not updated.
   end
   disp(PON)
   break
end

In what way is PON supposed to "update"? is it supposed to sum the values of "VAL" over the course of the loop?

What is the goal of your if statement? I doubt that (i>i+1) will ever be true.

The condition i>i+1 can never be true, so no wonder the line

PON=VAL(i+1);

is not executing. If it did execute, however, it would just over-write PON every time. Your code doesn't make it clear in what manner PON is supposed to "update" as new values of VAL are reached.

thankyou for the help sir, the statement

if(i>i+1)

was never true as you said. Thank you for the help.
