As Jordi as already mentioned, there's also the possibility of paying
someone to fix it for you (not unlike one would pay a plumber to fix
his house). I won't be able to do such thing but certainly someone on
the mailing list would.

How does it succeed in Matlab? This does not make sense. How can you
skip the optional parameters and jump into param/value? How can one
know if it's an optional parameter that does not validate or the key
for a parameter? I have no matlab access to experiment, I had to
deduce from their documentation. I asumed matlab would work this way
as I don't understand how it can be otherwise and this is documented
"see help inputParser"

As far as I know, no one is working on this at the moment. I know it's
not implemented but shouldn't be too hard to do it. The StructExpand
proprierty is already in place, it just doesn't do anything. When you
fix this, please do not forget to send us back a patch. Thanks in
advance.

By the way, if you are using octave's inputParser, take a look at
addSwitch which matlab hasn't implemented yet.
