Cell Arrays
Theexamplesinthissectionillustratehow to access the different components
of a cell array. All of the examples use the following six-cell array which
consists of different data types.
First, build the individual components of the example array:
rand('state', 0); numArray = rand(3,5)*20;
chArray = ['Ann Lane'; 'John Doe'; 'Al Smith'];
cellArray = {1 4 3 9; 0 5 8 2; 7 2 9 2; 3 3 1 4};
logArray = numArray > 10;
stArray(1).name = chArray(1,:);
stArray(2).name = chArray(2,:);
stArray(1).billing = 28.50;
stArray(2).billing = 139.72;
stArray(1).test = numArray(1,:);
stArray(2).test = numArray(2,:);
and then construct the cell array from these components using the { }
operator:
A = {numArray, pi, stArray; chArray, cellArray, logArray};
To see what size and type of array occupies each cell in A, type the variable
name alone:
A
A =
[3x5 double] [ 3.1416] [1x2 struct ]
[3x8 char ] {4x4 cell} [3x5 logical]
Manipulating Cells and the Contents of Cells
When working with cell arrays, you have a choice of selecting entire cells of an
array to work with, or the contents of those cells. The first method is called
cell indexing; thesecondiscontent indexing:
• Cell indexing enables you to work with whole cells of an array. You can
access single or multiple cells within the array, but you cannot select
anything less than the complete cell. If you want to manipulate the cells
