Is it possible to automatically comment few lines of matlab code after sometime while the code is running ?

Is it possible to automatically comment few lines of Matlab code after some time while the code is running? I think this will save execution time of my code, because I don't want Matlab to check 'if' condition everytime in a for loop once it is true.

Please help.

No, it is not possible to modify code while it is running.

Unless your if expression is extremely complex, I wouldn't even worry about it. It's unlikely to be a bottleneck. And if it is a worry, the first thing to do is check that it is indeed a problem using a profiler.

If the if check is expensive you can always shortcircuit it:

checkpassed = false;
for ...  %some loop
   if checkpassed || someexpensivecheck
        checkpassed = true;
        %...
    end
 end

because of the shortcircuiting behaviour of ||, once checkpassed is true, someexpensivecheck is never run.
