MATLAB function, nargout, in the method being called. The second input

argument is the input specified in the function declaration statement of

the

makesqr M-file.

Note The previous calling syntax is not the only way that you can call the

makesqr method. When Java B uilder encapsulates makesqr.m,itoverloads

the function, creating several signatures by which you can call the

makesqr

method. This lets you specify optional arguments when calling from Java.

See “Understanding Function Signatures Generated by Java Builder” on

page 2-6 for more details.

Note that the program uses a try-catch block to catch and handle any

exceptions.

9 Compile the application.

Compile the

getmagic application using the javac -classpath command

at the DOS or UNIX command prompt.

The compile yields a

getmagic.class file.

Note For matlabroot substitute the MATLAB root directory on your

system. Type

matlabroot to see this d irectory name.

a. On Windows, execute the fo llo wing command:

javac -classpath

matlabroot\toolbox\javabuilder\jar\javabuilder.jar;

.\distrib\magicsquare.jar getmagic.java

Note If you created the component using mcc, Java Builder does not

create a

\distrib directory to contain the .java file.
