So the question is just about comparing arrays of different sizes?
Maybe this way
a=ones(1000,1);
b=ones(900,1);
%b(10)=2; %change one element of b so a and b aren't equal
all(a(1:900)==b) %1 if they are equal and 0 if they aren't equal
It just compares the first 900 elements of a with those from b, the last 100 elements of a are just ignored
(I'm back after many weeks :) )
