Example: Magic S quare

Example: Magic Square

This example shows you how to:

• Access the online examples provided with MATLAB Builder for Java.

• Use MATLAB Builder f or Java to encapsulate a simple MATLAB function

in a Java component.

• Use the MWArray class library to handle data conversion in a sample

application.

About the Examples The examp les for MATLAB Builder for Java are in

matlabroot\toolbox\javabuilder\Examples.

The Magic Square example shows you how to create magicsquare,aJava

component, which contains the

magic class. The class encapsulates a

MATLAB function,

makesqr, which computes a magic square. It represents

the magic square as a two-dimensional array.

Thesampleapplication,

getmagic, does the following:

• Displaysthearrayreturnedbythe

makesqr method

• Converts the array returned by

makesqr to a native array and displays it

When you run the

getmagic application from the command line, y ou can p ass

the dimension for the magic square as a command-line argument.
