Using a WHILE loop for a trial and error solution.

You can't use this invalid syntax:

(0.05*Cm)<Pn<(0.05*abs(Cm))

You have to do it as two separate comparisons:

(0.05*Cm)<Pn && Pn <(0.05*abs(Cm))

Fix that and try it again.

Also, you tagged it as "infinite loop" - that's why robust code (like I write) always has a failsafe in there. For example you could have a loop counter and if it exceeds some number that you expect it to never exceed, bail out of the loop

counter = 1;
while someCondition
  % code
  counter = counter + 1;
  if counter >= 5000 % Some big number
    break;  % Fail safe - something went wrong so bail out!!!
  end
end % of while loop.
