I have several arrays and what I need to do is create a loop that calculates the values of the adition of each value of an array with each value of another array as show below:
Array:
A = [A1 A2 A3] B = [B1 B2 B3] C = [C1 C2 C3]
Needed Values:
D = A1+B1+C1 E = A1+B1+C2 F = A1+B1+C3 G = A1+B2+C1 H = A1+B2+C2 I = A1+B2+C3 .... and so on
On a side note, what is the MATLAB notation for a specific value of an array such as A(1) = A1

One way using implicit array expansion:
D = A(:) + reshape(B,1,[]) + reshape(C,1,1,[]);
Your results are the elements of D.
I'm not sure what you are asking about A(1) vs A1. A(1) is the MATLAB notation for the 1st element of variable A. A1 would be the name of a different variable ... it has no relationship to variable A.

A = [1 2 4];
B = [8 16 32];
C = [64 128 256];
D = reshape(A, 3, 1) + reshape(B, 1, 3) + reshape(C, 1, 1, 3)
[A(2)+B(3)+C(1), D(2, 3, 1)]
