% Script with basic examples of using cells and structs in Matlab.
% One point is that cells are defined/indexed using {} instead
% of (), and that what you get back is a cell, not the contents of 
% the cell. Also, structs can be considered as heterogenous arrays
% versus the usual Matlab arrays, which require every element in
% them to be of the same type.
