You already have, by storing your data in a matrix.
A = magic(5)
% Data associated with the number 3
A(3, :)
If you have different requirements for your numbering that the row indices do not satisfy, please state those requirements.

Yes, this is doable. To show the entire matrix with the line number (row index) shown first on each line:
>> n = 5;
>> A = magic(n);
>> [(1:n)' A]
ans =
1 17 24 1 8 15
2 23 5 7 14 16
3 4 6 13 20 22
4 10 12 19 21 3
5 11 18 25 2 9
