Try this (untested because you didn't attach your text files):
a = dlmread('test4.txt');
b = dlmread('test5.txt');
c =(a-b)>125; % Logical array
a(c) = 0; % Replace elements in a with 0;
b(c) = 0; % Replace elements in b with 0;
% Write updated a and b back out.
dlmwrite('test4.txt', a);
dlmwrite('test5.txt', b);

Use my code in the comment, but have C be this:
c = a ~= b; % Logical array
This will calculate where a and b are different, like you asked for.
