Sat 19 Nov 2016 08:21:22 PM UTC, comment #4: This issue is still present in Octave 4.2.0.	Hartmut <hardy>
Fri 16 Mar 2012 07:22:17 AM UTC, comment #3: Wouldn't it be possible to intercept the error by just giving the nargin function a list with the builtin funtions names and their respective number of expected arguments? The numbers shouldn't change. I know its ugly to keep this consistent but for the meantime it would do the job.	Anonymous
Fri 02 Mar 2012 06:21:39 PM UTC, comment #2: The definitions of built-in functions do not include the number of expected arguments (assuming that number is fixed). So fixing this will require modifying the way built-in functions are defined.	John W. Eaton <jwe>
Fri 02 Mar 2012 05:32:19 PM UTC, comment #1: On the development branch the warning has already been updated to be more specific. nargin ('abs') error: nargin: nargin information not available for builtin functions I'm guessing that this has been a known issue for a while and that there is not an easy workaround. :(	Rik <rik5>
Fri 02 Mar 2012 03:28:15 PM UTC, original submission: When calling nargin with a built-in function name (e.g. "nargin('abs')" ) it returns an error stating "error: nargin: FCN_NAME must be a user-defined function" For example, in Matlab "nargin('abs')" returns 1.	Anonymous
