To do so, use lists within lists. That is, make a listwhere each element is a list that contains the elements of one row of thearray. Thus, you could define the pwrs array as follows.> pwrs2 := array( 1..3, 1..3, [[1,1,1], [2,4,8], [3,9,27]] );⎡ ⎤1 1 1pwrs2 := ⎣ 2 4 8 ⎦3 9 27Arrays are by no means limited to two dimensions, but those of higherorder are more difficult to display. You can declare all the elements of thearray as you define its dimension.> array3 := array( 1..2, 1..2, 1..2,> [[[1,2],[3,4]], [[5,6],[7,8]]] );
