jobStartup - File for user-defined options to run when job starts

Syntax

jobStartup(job)

Arguments

job

The job for which this startup is being executed.

Description

jobStartup(job) runs automatically on a worker the first time that worker evaluates a task for a particular job. You do not call this function from the client session, nor explicitly as part of a task function.

You add MATLAB code to the jobStartup.m file to define job initialization actions on the worker. The worker looks for jobStartup.m in the following order, executing the one it finds first:

Included in the job's FileDependencies property.
In a folder included in the job's PathDependencies property.
In the worker's MATLAB installation at the location
```
matlabroot/toolbox/distcomp/user/jobStartup.m
```

To create a version of jobStartup.m for FileDependencies or PathDependencies, copy the provided file and modify it as required. For further details on jobStartup and its implementation, see the text in the installed jobStartup.m file.
