MATLAB doesn't have anything similar, AFAIK, but the following will
work:

def xzeroaxis(form=3D'k'):	# draw a line at y=3D0 on the current plot
   v=3Daxis()
   plot(v[0:2],[0,0],form)

def yzeroaxis(form=3D'k'):
   v=3Daxis()
   plot([0,0],v[2:4],form)

Is this worth adding to the distribution?  I doubt it is general enough
to warrant.

John:  when I do the following:
v=3Darange(-5,5)
plot(v,v**3)
xzeroaxis()
yzeroaxis()

the vertical line at x=3D0 doesn't quite go to top and bottom of the
plot.  This is with 0.62.4.
