This page contains information about using EPICS with MATLAB R2019a and Java in the LCLS Development and Production environments.
Attention:
All scripts in this page are assuming that your current shell is Bash.
In order to change your default shell at login from tcsh (or any other shell) to Bash, please execute the following command on a Linux server on the AFS network, such as a rhel6-64* node. (You will be prompted for your password during this process):
|
After that, close the terminal and open a new one. You will be using Bash as the default shell.
You can check if all went well with the following command in a new Terminal window:

For MATLAB admins (epicsmgr group members) only:
At the time of this writing, the latest version of MATLAB deployed for LCLS Development and Production is 2020a.
Individual AFS user accounts in the LCLS Development environment default to set up and use MATLAB 2012a unless overridden.
The default MATLAB versions for shared login accounts in Production are as follows:
Account | Default MATLAB version |
---|---|
physics | 2012a |
softegr | 2019a |
laci | 2012a |
This is 64-bit software.
The Java version used by this Matlab is Java 8.
In order to set up your environment to use one of the supported versions of MATLAB, follow one of the appropriate procedures below.
Development
Do not run MATLAB instances on mcclogin or lcls-prod02. MATLAB should be run on mcc-simul in DEV.

For the Development and Production environments, a set of working configuration files is already provided for users and invoked upon login. Users can override the usage of these files by having their own custom files in the folder where they launch MATLAB (see: Creating A Custom MATLAB Environment).
MATLAB is non-standard Unix software and does not adhere to values set by PATH, LD_LIBRARY_PATH, CLASSPATH, and other global environment variables that are used by most other Unix software. Instead, MATLAB uses the following configuration files to set its environment:

If you need to use a MATLAB environment configuration that does not match the default environment provided in Development or Production, you will need to create your own java.opts, classpath.txt or librarypath.txt files in your working directory prior to launching MATLAB.
It is strongly recommended to only override the files needed in your local workspace, since MATLAB will inspect your current working directory before looking at the global configuration files.
If you need to connect to a different set of EPICS servers, copy the java.opts file from one of the locations above to your local working directory and modify it according to your needs.
If you need to test a new JAR file, copy the classpath.txt file from one of the locations above to your local working directory and modify it according to your needs.
If you need to test a new library to add to the library path, copy the librarypath.txt file from one of the locations above to your local working directory and modify it according to your needs.
Never try to modify the existing global configuration files. If you need changes made to the global configuration files, consult the MATLAB admins for LCLS Development and Production (TID-ACS and EED Systems Group). Any changes to the global MATLAB configuration must be approved and implemented by those groups.
