I have the following equation,
function EI=GetEI(x)
E(1)=x(1);
E(2)=x(2);
E(3)=x(3);
EI=32*E(1)+E(2)/30+32*E(3);
I have the values of E1, E2 and E3, There are 12^3 (each E has 12 possible values) permutations and answers and I want to get all of the possible answers. I need help to write a code to get my values, can anyone help?

Why not try a loop? Actually, try THREE nested loops. TRY SOMETHING. If you are a beginner, this is how you will learn. And if you make and show some effort, then you might get better help.

In general you can try like this.
If E1, E2, E3 are arrays of size 12, then
for i = 1:12
for j = 1:12
for k = 1:12
EI=32*E1(i)+E2(j)/30+32*E3(k);
end
end
end
