"error: Invalid call to rgb2ind.  Correct usage is:

 -- [X, MAP] = rgb2ind (RGB)
 -- [X, MAP] = rgb2ind (R, G, B)

Looking at the function calling structure on matlab:

[X,map] = rgb2ind(RGB,n)
X = rgb2ind(RGB, map)
[X,map] = rgb2ind(RGB, tol)
[___] = rgb2ind(___,dither_option)

and octave:
[x, map] = rgb2ind (rgb)
[x, map] = rgb2ind (R, G, B)

it appears that the current Octave implementation is not fully compatible. Unless there's already something on the bug tracker that I didn't see in a quick search, it should probably be logged as one:
