How to stop a script if conditions are met.

1.366 visualizzazioni (ultimi 30 giorni)
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.

Hi Cory, have you solved this problem? I think I encountered the same problem...

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 think a 'msgbox' to really alert the user what is the issue, and then the 'error' funcition to stop the code would be a workaround. This way the user is aware that the issue is not really an 'error' when they see the red error font.
msg = "You've got a number that is not 5 digits long";
f = msgbox(msg)
error(msg)

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.
