Post the simplest code that reproduces your problem here
http://agora.octave.org/snippet/

>From the error you sent it is simply that you are calling rgb2ind incorrectly
The code you send in the link uses

[mytext,map]=rgb2ind(A,256);

But as you see from the error rgb2ind in Octave can't be called like
that. You have ti understand what is that line supposed to do and then
do the equivalent in Octave.
Hope that helps.
