y=2
rr=[1,2,3,4,5]
horzcat(rr,y)
y =
2
rr =
1 2 3 4 5
ans =
1 2 3 4 5 2
Note that this requires that your inputs are both row vectors -- or at least that whatever they are has the same number of rows.
If you are adding new rows to an array see vertcat(), which requires that whatever the inputs are has the same number of columns as each other.
If you do not know ahead of time whether the inputs are row vectors or column vectors or that they are the same as each other , then provided they are both vectors, you can use
newrr = rr;
newrr(end+length(y)) = y;
This will have the same orientation as rr has.
