NARGIN  NARGIN Number of Input Arguments


Usage
 
 The special variable nargin is defined inside of all
 functions.  It indicates how many arguments were passed
 to the function when it was called.  FreeMat allows for
 fewer arguments to be passed to a function than were declared,
 and nargin, along with isset can be used to determine
 exactly what subset of the arguments were defined.
 There is no syntax for the use of nargin - it is 
 automatically defined inside the function body.
