Re: [newbie] how to make a function perform differently depending on output asked for

[Olivier Crouzet]

Hi,

you may also have a look at the bode.m function source code:

/usr/share/octave/packages/control-2.6.6/bode.m (in Debian; the base
directory may vary),

which will give you insights into how the bode.m function itself is
designed (and have a look at the nargout expression). It uses 

if (! nargout)
[...]
else
[...]
endif

Which will let you 
Olivier.
