How to deploy a specific version of matlab when there are two versions installed on Linux?

Hi all,

I have two versions of matlab installed in Linux ubuntu (15a and 19a).

Once I type matlab on terminal, the 2019 version pops up. How to deploy the older version instead? How can I choose between them through terminal?

Thanks guys.

The easiest way I found was using the terminal is going to the bin of MATLAB folder.

Mine is located in /usr/local/MATLAB/R20xx/bin.

In MATLAB you're gonna find all the versions installed in your computer.

After choosing the one you want to deploy, go into the bin folder of the chosen version and type ./matlab

I want to give rise to a particular concern that your approach is, of course, easy but it does not initialize a clear and separated environment for each Matlab version. By your approach, you must expect that the launched Matlab versions are not dynamically linked against the correct libraries, which may cause a crash.

I recommend to use the Environment Modules package from

Modules

that allows to alter or to set shell environment variables such as PATH, MANPATH etc. After installation and configuration one can call a specific version of Matlab by executing in the shell

module load matlab/R2019a

For changing the version one has to unload first the previous loaded Matlab version by

module unload matlab/R2019a

and then one needs to load the other version by

module load matlab/R2015a

You can go into FileExplorer to the folder of the one you want to launch, and double click it.

To clarify, you need to go to /MATLAB/20XXX/bin where you will find matlab.exe

where the 20XXX is the version that you want to open.

Note that the question asks about Ubuntu, where .exe files do not exist.

The relavent directory on (many) linux installations would be /usr/local/MATLAB/version/bin
