Run a Batch Job

To offload work from your MATLAB session to run in the background in another session,

you can use the batch command. This example uses the for-loop from the previous

example, inside a script.

To create the script, type:

edit mywave

In the MATLAB Editor, enter the text of the for-loop:

for i = 1:1024

A(i) = sin(i*2*pi/1024);

end

Save the file and close the Editor.

Use the batch command in the MATLAB Command Window to run your script on a

separate MATLAB worker:

job = batch('mywave')

MATLAB

client

MATLAB

worker

batch

The batch command does not block MATLAB, so you must wait for the job to finish

before you can retrieve and view its results:

wait(job)

The load command transfers variables created on the worker to the client

workspace, where you can view the results:

load(job,'A')

plot(A)

When the job is complete, permanently delete its data and remove its reference from

the workspace:

delete(job)

clear job
