Sixth Section

6. Cells and Structures

Structures are collections of different kinds of data organized by named

fields. Cell arrays are a special class of Matlab arrays whose elements

consist of cells that themselves contain Matlab arrays. Both structures and

cell arrays provide a hierarchical storage mechanism for dissimilar kinds of

data. They differ from each other primarily in the way they organize data.

You access data in structures using named fields, while in cell arrays data is

accessed through matrix indexing operations [2].

6.1 Cells

A cell array is a Matlab array for which the elements are cells, containers

that can hold other Matlab arrays. For example, one cell of a cell array might

contain a real matrix, another an array of text strings, and another a vector

of complex values [2]. Moreover, you can build cell arrays of any valid size or

shape, including multidimensional structure arrays. Figure 14 gives an

illustration on how a 2-by-2 cell array might look.
