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.
