indexing cells arrays

This example shows how to read and write data to and from a cell array. To run the code in this example, create a 2-by-3 cell array of text and numeric data:

C = {'one', 'two', 'three';
     1, 2, 3};

There are two ways to refer to the elements of a cell array: 

1. Enclose indices in smooth parentheses, (), to refer to sets of cells—for example, to define a subset of the array.
2. Enclose indices in curly braces, {}, to refer to the text, numbers, or other data within individual cells.
