Hi
It wasn't a typo, but from what I understand the comma isn't necesary. The problem is related to the call to ind2gray.

Thanks,
Søren

May just be a typo on your email, but you have no comma..
    [indexed map] = gray2ind(I);

should be..
    [indexed, map] = gray2ind(I);

Hi
Shouldn't I be able to do the following? ('I' as 512x512
image)

  [indexed map] = gray2ind(I);
  G = ind2gray(indexed, map);

If I do the above I get this error:

error: invalid vector index = 15436
error: evaluating argument list element number 1
error: evaluating assignment expression near line 49,
column 5
error: called from `ind2gray' in file
`/usr/share/octave/2.1.64/m/image/ind2gray.m'
error: evaluating assignment expression near line 48,
column 3

But perhaps I'm misunderstanding the functions?
