How do I create matrix of Linked lists

Hi, I have a matrix and for each cell in the matrix I need to save data with different length. I think that using Linked lists structure will be useful, because the length of the data for each cell is changing in each iteration (can be bigger or smaller). My problem is how to give names for the Variables in each iteration (n1, n2, n3, ...) that will be with meaning and easy to find later? Or a different and useful way to organize the data.

Thanks Yuval.
