NARGOUT NARGOUT Number of Output Arguments

Usage

The special variable nargout is defined inside of all
functions.  It indicates how many return values were requested from
the function when it was called.  FreeMat allows for
fewer return values to be requested from a function than were declared,
and nargout can be used to determine exactly what subset of 
the functions outputs are required.  There is no syntax for 
the use of nargout - it is automatically defined inside 
the function body.
