Sum two arrays using logical indices

I want to sum two arrays

a = [ 1 2 3];
b = [2 3 1 ];
a_logical = [0 1 0];
a_logical = ~a_logical;
b_logical = [1 0 0];
b_logical = ~b_logical;

I want the sum of a + b to be

[ 1 0 3] + [0 3 1] = [1 3 4]

Any suggestion on how the above sum can be obtained using the logical indices stored in a_logical and b_logical?

Can you elaborate more?

>> [ 1 0 3] + [0 3 1]
ans =
     1     3     4

Answer 1

[KALYAN ACHARJYA]

c=a.*(a_logical)+b.*(b_logical)

c =

     1     3     4

Answer 2

[JESUS DAVID ARIZA ROYETH]

Could it be that way? :

a (or (a_logical, b_logical)) + b (or (a_logical, b_logical))
