Octave additions.

This is an Octave only feature.  We can either blacklist, or visually skip
over the comparison since it is blank for Matlab.

It should be datetick (2, 'x', 'keepticks').  The demo block is trying to
test that you can use an axes handle as the first argument.  In Octave, 'x'
is always the default axis and doesn't need to be re-specified.  In Matlab,
it appears you do need to do this.

Does Matlab accept this?
legend (h, 'location', 'northeastoutside')

This is an Octave-only feature.  Maybe put the if statement that generates
this in a try/catch block.

All fine.  Matlab doesn't have the stemleaf function.

Matlab has deprecated delaunay3 in favor of just delaunay which accepts 2-D
and 3-D data.  Octave hasn't made that switch yet.
