Stem.m exists/is available via octave-forge. See below.
octave:2> help stem.m

stem.m is the file:

usage: stem(x, [,y] [, linetype])

Draws struts for each point, overlaid on another line type. This is
    plot(x, y, linetype, x, y, "^;;")
but with the pointsize increased so that you can see the symbols
clearly.  By default, linetype is "o;;" so that circles are
connected to the x-axis with struts.

Note that a plot can only support one point size, so if you are
plotting multiple plots, do stem last to keep large points.

   t=0:0.1:2*pi; x=sin(t); idx=1:4:length(t);
   plot(t,x,"r-+;sin(x);"); hold on
   stem(t(idx), x(idx),"bo;struts;"); hold off

Additional help for built-in functions, operators, and variables
is available in the on-line version of the manual.  Use the command
-- less -- (f)orward, (b)ack, (q)uit
