Error between each pixel for two matrices of equal size

Hi
I'm trying to find the error between to matrices of equal size. Let's say that my matrices are of size 4x4 :
A = [0 1 0 0; 1 1 0 0; 0 1 0 1; 0 1 1 0];
B = rand(4,4);
How would you find the error between each pixel of those matrices?

Wouldn't it just be
theError = A - B;
Caution: don't use error for the variable name since that is the name of a built-in MATLAB function.

Is this what you want
A = [0 1 0 0; 1 1 0 0; 0 1 0 1; 0 1 1 0];
A =
0 1.00 0 0
1.00 1.00 0 0
0 1.00 0 1.00
0 1.00 1.00 0
B = rand(4,4)
B =
0.62 0.59 0.76 0.08
0.47 0.55 0.75 0.05
0.35 0.92 0.38 0.53
0.83 0.29 0.57 0.78
>> out = A - B
out =
-0.62 0.41 -0.76 -0.08
0.53 0.45 -0.75 -0.05
-0.35 0.08 -0.38 0.47
-0.83 0.71 0.43 -0.78
