You already have, by storing your data in a matrix.
A = magic(5)
A = 5×5
17 24 1 8 15 23 5 7 14 16 4 6 13 20 22 10 12 19 21 3 11 18 25 2 9
% Data associated with the number 3
A(3, :)
ans = 1×5
4 6 13 20 22
If you have different requirements for your numbering that the row indices do not satisfy, please state those requirements.
