Hi everyone
I need to stop a program before it reaches to the end of the script but it is not allowed to use retun and go to. I know that "error" command is available but it spits out "error in line ..." in command window and it is not allowed either. Sorry it seems weird but it is an assignmnet with restricting instructions.
Thanks for the time

Can you post the assignment? The requirements seem very strange, as Jan pointed out in his answer.

Who forbids useful commands?!? Is it an anti-homework to teach bad programming styles?
function myTest
for unused = 1
disp('Hello');
break
disp('Hello again'); % Not reached
end
end
Alternatives to the break in a pseudo-loop:
exit (kills the complete Matlab sessions, but "stops the program"), quit (the same), try/catch/end (to let the code stop by error() without displaying a message. Or:
function myTest
s = input('Please type in the command: ', 's');
eval(s);
disp('Hello again'); % Not reached
end
So just type in 'return'... (evil)

Ha... or just type in "format this hard-drive, reboot" (very evil)

Use break
t = 0;
for k = 1:2000
if isprime(k) & isprime(k-5)
break
end
t = t + 1;
end
