Yes, Julia doesnt have "nargout". The idiomatic way to do this would be to use optional arguments:
http://julia.readthedocs.org/en/latest/manual/functions/#optional-arguments So: function f(a, b=0) if b > 0 #do the computations for second argument end #rest of computation end Use a default value that makes sense in your domain.
