I am using the 'if' function to detect if a user inputs a number that is not 5 digits long. What I would like is a function that stops the script if a certain condition is met without displaying an error message.

P.S. I'm very new to MATLAB.

To stop running a script or function and return to the invoking function or command window, use the return function. For example,

if a > b
   return
end

Any code in the current script or function that is after the return function is not run

notdone = true(9,1);
while any(notdone)
    if  rcp(i,m)<0.1 & trcp(i,m) > 0.8
    ECP{i,m}=Ecp{i,m};
    notdone(1) = false;
  end
  if  recp(i,m)<0.1 & trecp(i,m) > 0.8
    ECN{i,m}= Ecn{i,m};
    notdone(2)=false;
  end
%etc
end

you may use "error" function instead of return

I wonder if it is possible to detect if the code is running in a try block. In such cases the message might be more confusing than simply throwing the error.
