How do I create an indexible set of 2D arrays with differing dimensions

I have a function that scans a directory containing n csv files of dimension Xrows x Ycolumns where Xrows>1 and Ycolumns = either 5 or 35.and

It calculates a two dimensional result array of size f(Xrows,Ycolumns) for each file that meets certain criteria,

How can I creat an indexable set RESULT of these result arrays so we can generate a series of different types of plots for each result array? I suspect we want some type of structure, but I'm new to Matlab so not sure how to define and populate such a structure.

Thanks

cell array, probably.
