How can I test for a return in 2010a

Hello everyone,

I have a program that calls a function. I would like to put a test in this function that would call "return" is true. however, that function is called in a loop so I would like to test if the function was ended prematurely and call "break" on the loop.

something along the lines of that:

if return==true

break

else

...

Is there anyway to actually do that?

The function you call is a MATLAB function? is it a function you code? if the function end prematurely, is it due an error?

I coded the other function, it has to stop because otherwise it starts looking outside an vector, hence creating an error and stopping the whole thing

Sure...just add another return variable flag and test it...

function [other return vars flag]=yourfunction(inputs)
  ...
  flag=false;
  ...
  % oops, an error or something happened
  if bomb_condition
    flag=true;
    return
  end
  ...

Use like

...
[var1, flg]=yourfunction(x);
if flg, break, end
...

Right! how did I not think of that?

Thanks a lot!
