• New versions (versions later than 2012a) of MATLAB should be installed in the 3rd-party software package area under the matlab folder:
  - Development: /afs/slac/g/lcls/package/matlab
  - Production: /usr/local/lcls/package/matlab
• Inside the matlab directory, versions should be installed in folders that correspond to their MATLAB version, e.g. 2012a, 2019a, 2020a, 2022b, 2023a, etc.

At the time of this writing, the latest version of MATLAB deployed for LCLS Development and Production is 2022b2023a.

Individual AFS user accounts in the LCLS Development environment default to set up and use MATLAB 2012a 2020a unless overridden.

The default MATLAB versions for shared login accounts in Production are as follows:

2022b

This is 64-bit software.
The Java version used by this Matlab is Java 8.

  • /afs/slac/g/lcls/package/matlab/2022b
• Production
  • /usr/local/lcls/package/matlab/2022b
  • In production, make sure to copy the licenses folder from other MATLAB version:
    /usr/local/lcls/package/matlab/2022b/licenses
