The current implementation of rgb2ind is incompatible with the one
from matlab. The behaviour when it has 2 arguments depends if the
second argument is a colormap or a scalar but Octave currently
supports none of them. Plus, rgb2ind is completely broken since it
does not even return a valid colormap (exception made for rgb of class
double which I find to be very rare). I have submitted some patches
that will at least fix that last week
https://savannah.gnu.org/bugs/?37712

But supporting the other arguments as with matlab will require some
extra input checking if we don't want to break current code (which may
try to pass each channel as independent variables).
