@Valentina's comments, I have added functions for multiplying and dividing polynomials.

I forgot to put it in the readme. Actually, you are supposed to load the image first. Watching this should help http://www.youtube.com/watch?v=1vpsn2BJ1bE

Hi Samuel,
I'm trying to use this code to perform some AES operations... What I need is e.g. to define a polynomial which can have a max degree = 7, with coefficients 0 and 1. (i.e., over GF(2)), and then compute its inverse modulo a poly of degree 8, again with binay coeffs. I can't figure out how to declare the gf, which in your example is gf9=gf(3,2); and then how do i define the poly? what does the 2 line matrix in your example mean, a=[2 1;1 0]?
Thanks!

Hi, Samuel ,I don't know what happened with your code in Matlab. When I typed 'sui_gui', nothing happened and too many errors. Do you have email. I want to ask you some question. Thank you.

Using R2010a, it doesn't work for me. Clicking most of the buttons (such as the 1x, 2x ...) result in error messages, such as:

??? Reference to non-existent field 'start_pos'.

and

??? Reference to non-existent field 'images'.

To be more concrete, I can generate the latter error message by:
(1) running "sr_gui"
(2) clicking the "register images" button

I'm not sure if this is because another button needs to be clicked first; if that is the case, then maybe a useful warning message can be generated.
