My guess:

% matrix as in 1.png:
data = reshape(1:21,3,[]).'

data = 7×3

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

% new columns to be added:
new_data = (4:9)+3*(0:6).'

new_data = 7×6

4 5 6 7 8 9 7 8 9 10 11 12 10 11 12 13 14 15 13 14 15 16 17 18 16 17 18 19 20 21 19 20 21 22 23 24 22 23 24 25 26 27

% append the new columns to the end of data matrix:
data = [data new_data]

data = 7×9

1 2 3 4 5 6 7 8 9 4 5 6 7 8 9 10 11 12 7 8 9 10 11 12 13 14 15 10 11 12 13 14 15 16 17 18 13 14 15 16 17 18 19 20 21 16 17 18 19 20 21 22 23 24 19 20 21 22 23 24 25 26 27

You really don't give enough detail about what you are trying to do. You are making us assume and/or guess too much. Maybe you want the reshape command?
