function comb(x,y,linetype)
%COMB	Plot discrete sequence data.
%	COMB(Y) plots the data sequence Y as stems from the x-axis
%	terminated with circles for the data value.
%	COMB(X,Y) plots the data sequence Y at the values specified
%	in X.
%	There is an optional final string argument to specify a line-type
%	for the stems of the data sequence.  E.g. COMB(X,Y,'-.') or
%	COMB(Y,':').
