Problem with calling function; too many outputs

Hi, after I updated Octave from 6.4 to 7.2 I get an error while trying to call function:

octave.in_data_gen(a, 'A.txt', L, N)

Output:

  File "/home/vm/.local/lib/python3.11/site-packages/oct2py/dynamic.py", line 103, in __call__
    return self._ref().feval(self.name, *inputs, **kwargs)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/vm/.local/lib/python3.11/site-packages/oct2py/core.py", line 392, in feval
    return self._feval(func_name, func_args, dname=dname, nout=nout,
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/home/vm/.local/lib/python3.11/site-packages/oct2py/core.py", line 595, in _feval
    raise Oct2PyError(msg)
oct2py.utils.Oct2PyError: Octave evaluation error:
error: in_data_gen: function called with too many outputs
error: called from:
    in_data_gen at line -1, column -1

The function was working fine before the update and is working fine when being used in Octave directly. Function is very simple, doesn't return anything; only does some type cating and writes a txt file.

I've done some more testing and the problem only occurs when the function matlab function called by oct2py does not return any value. When the same function is modified to return some value everything works fine.

Ok, I've been able to fix the issue by adding an additional argument when calling function nout=0. Presumably I should have thought about it earlier. Sorry for making fuss. Hope that this will help anyone migrating their code to newer version of octave.
