在 MATLAB Online 中打开

Hi @Tayeb, to use a previous version of MATLAB you need to visit the 'downloads' page on the official MathWorks website. Here you can download the version you require after selecting it from the dropdown. Here is the link for the page: https://www.mathworks.com/downloads/

In general, to launch MATLAB R2021a, navigate to the folder where MATLAB was installed and run the '.exe' file directly.

To run the older version (on Windows) using a cmd command, open the Command Prompt, type the command below, and press enter.

"C:\Program Files\MATLAB\R2021a\bin\matlab.exe"

If you already have the older version installed (on Windows), just change the order of the 'System Environment Variables'. Navigate to Edit the system environment variables > Environment Variables ... > System Variables > Path and edit the 'Path' variable to move the path to MATLAB R2021a above the path of MATLAB R2022b.
