MATLAB does not launch correctly

I have installed MATLAB 2023b and I already have MATLAB 2022b. When I tried to launch MATLAB 2023b, unfortunately, MATLAB 2022b launched instead.

I really appreciate any help.

Thanks in advance.

Could you provide more information on how you are trying launch MATLAB 2023b, as in through the command line or the application.exe file and so on?

then

(base) draadel@draadel-OMEN-by-HP-Desktop-PC-880-p1xx:/usr/local/MATLAB/R2023b/bin$ matlab

From the bin directory of the MATLAB version that you want to use, try:

./matlab

To run from anywhere an executable specified only by name, you can add the path to the directory containing the executable to the list of paths assinged to the environment variable PATH, making sure that it's ahead of the paths to any other directories containing an executable of the same name.

You can check how you have PATH defined with:

echo $PATH

You can check the path that will be used if you specify the name matlab with:

which matlab
