Assume two column vectors with same number of rows:
1 4
2 3
3 2
4 1
I would like to average each row and store this in a new variable hence will be:
2.5
2.5
2.5
2.5

The mean command has an option to average in a specific dimension.
A = [1 4;
2 3;
3 2;
4 1];
B = mean(A,2);

If you have 40 rows, aren't you going to end up with 40 results no matter what? Do you not want the average for all individual rows?
As for the two separate vectors, just combine them.
A = [1; 2; 3; 4];
B = [4; 3; 2; 1];
C = [A, B];
D = mean(C,2);
