matrix creation

[fidippide]

good evening to all, I have created two rows of holes in a conduit and I would like to repeat them equal 9 times along the same. I can't use the rectangular matrix command; It's confusing. How could I do that? Thank you very much!

the error that gives me is the following:

the problem arises from the fact that the matrix requires only one feature hole instead of multiple rows of holes...a solution could be:
run a hole
run a circular matrix (to make the row of holes)
perform a rectangular matrix (for repetition)
idem for the second row
finished
