Do you want a row by row comparison?

Do you want to compare the 1st with the 1st, the 2nd with the 2nd etc, or the 1st with the 2nd also?

G = randi(3, 45, 2);
I = randi(3, 45, 2);
sum(all(G == I, 2))

If G and I are floating point arrays, you need to be aware of the FAQ http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F so that you check for tolerance rather than exact equality.
