MATLAB: Leave the whole for-loop

breakfor loopif statementloops

How can I leave the loop completely, if an "if" statement in that loop turns out to be true? I have tried break, but I guess that doesn't work in if-structures… My code structure looks like this:
 for i = 1:5
      (doing some stuff here)
     if [something happens]
         for [...], for [...], (assignments); end, end, 
                    !and STOP COMPLETELY no further calculations are needed!
     else
         for [...], (assignments ); end
     end 
   (doing more stuff)
end
Thanks for any help!

Why can't you use break? The break command can perfectly be used in combination with if statements. Break will execute the innermost for (or while) loop it is in...
Consider the following example:
   for ii = 1:10
       disp(['Current value of ii = ', num2str(ii)])
       if ii>5
           % execute some for loops
           for kk=1:5
               for ll=1:5
                   % put your commands here
               end
           end
           % exit the for loop
           break 
       else
           for kk=1:5
              % do something here 
           end
       end 
   end
   disp(['for loop was stopped at the moment that ii = ', num2str(ii)])
The break command will exit the innermost loop (type: help break):
break Terminate execution of WHILE or FOR loop.
    break terminates the execution of FOR and WHILE loops.
    In nested loops, break exits from the innermost loop only.
Does this clarifies it for you?
