Dynamic execution of MATLAB models and collection of results. The idea here is to execute MATLAB functions from Java.

Installation

MathWorks MATLAB Java Engine

1. Locate MATLAB installation directory, <matlab_root>:
   • On MacOS, this is /Applications/MATLAB_R2021a.app
   • On CentOS, CSU Lab machines /s/parsons/l/sys/matlab
2. Add MATLAB architecture to system environment variable:
   • Documentation for this step: https://www.mathworks.com/help/matlab/matlab_external/setup-environment.html
   • On MacOS, this is <matlab_root>/bin/maci64
     • Add export DYLD_LIBRARY_PATH="/Applications/MATLAB_R2021a.app/bin/maci64" to .zshrc or .bashrc
   • On CentOS, CSU Lab machines <matlab_root>/bin/glnxa64:<matlab_root>/sys/os/glnxa64
     • Add export LD_LIBRARY_PATH="/s/parsons/l/sys/matlab/bin/glnxa64:/s/parsons/l/sys/matlab/sys/os/glnxa64" to .zshrc or .bashrc
3. Locate Java engine jars within:
   • <matlab_root>/java/jar
4. Add required jars to Gradle/Maven dependencies:
   • Example for Gradle on MacOS:

dependencies {
   implementation files('/Applications/MATLAB_R2021a.app/java/jar/engine.jar')
   implementation files('/Applications/MATLAB_R2021a.app/java/jar/javaenginecore.jar')
   implementation files('/Applications/MATLAB_R2021a.app/java/jar/matlab.jar')
}
