Converting to a MATLAB Cell Array

Use the cell function to convert a Java array or Java object into a MATLAB

cell array. Elements of the resulting cell array will be of the MATLAB type (if

any) closest to the Java array elements or Java object.

The syntax for the

cell command is as follows, where object is a Java object

or Java array of objects.

cell(object);

In the following example, a MATLAB cell array is created in which each cell

holds an array of a different data type. The

cell command used in the first line

converts each type of object array into a cell array.

import java.lang.* java.awt.*;

% Create a Java array of double

dblArray = javaArray('java.lang.Double', 1, 10);

for m = 1:10

dblArray(1, m) = Double(m * 7);

end

% Create a Java array of points

ptArray = javaArray('java.awt.Point', 3);

ptArray(1) = Point(7.1, 22);

ptArray(2) = Point(5.2, 35);

ptArray(3) = Point(3.1, 49);

% Create a Java array of strings

strArray = javaArray('java.lang.String', 2, 2);

strArray(1,1) = String('one'); strArray(1,2) = String('two');

strArray(2,1) = String('three'); strArray(2,2) = String('four');
