5 Sample Applications (Java)

2 If you have not already done so, set the environment variables that are

required on a d ev elo pm ent machine. See “Settings for Environment

Variables (Development M achine)” on page 6-2.

3 W rite the M-code that you want to access.

This example uses

computefft.m and plotfft.m, which are already in

your work directory in

SpectraExample\SpectraDemoComp.

4 Specify a Java component as follows :

a. While in MATLAB, issue the following command to open the

Deployment Tool dialog box:

deploytool

b. Create a new project with t he se settings:

Field Value

Component

name

spectralanalysis

Class name fourier

Show verbose

output

Selected

c. Add the plotfft.m M-file to the project.

Note In this example, the application that uses the fourier class

does not need to call

computefft directly. T he computefft method

is required only by the

plotfft method. Thus, when creating the

component, yo u do not need to add the

computefft function, although

doingsodoesnoharm.

d. Save the project. Make n ote of the project directory because y ou w ill

refer to it later when you build the program that w ill use it.

5 Build the component.
