MATLAB: Is it available to change the end of a loop for inside it

endvalfor loopMATLAB

the size of my variable out changes inside the loop for so that's why I recalculate it inside it but the loop variable i stops in the first size of the variable even sizeOut changes.

can't the endval of the loop change ? or it can't ?

You want to use a while loop for this purpose.

It might look something like this (tough to tell without seeing more of your code)

c = 2;      %counter
while c <= sizeOut(1,1)
    % Do something
    c = c+1; 
end

Another good suggestion by Stephen Cobeldick is to add a conditional break to the for-loop that exits the loop when the sizeOut variable reaches a certain size.

Use the continue command.

If you want to break out of the loop entirely (based upon some condition), use the break command.

MATLAB: Leave the whole for-loop

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?
