Hi all,

I am doing a course on MATLAB/Simulink by Udemy but unfortunately I am having an error in setup of MATLAB r2020a on my laptop. I wanna know if can use MATLAB r2020a online to continue my course?

@Paul Edson

You need to visit https://www.mathworks.com/downloads/ .

If you have a license that is eligible for downloading, then on the left hand side there will be a "Select Release" . You might need to click on "Show More" to have R2020a show up in the list. If it does not show up then you are not eligible to download R2020a. Once you have clicked on R2020a, a download link will appear in the center of the page.

Not sure we can answer your question without knowing what is in the course and whether or not you have access to MATLAB Online. You can contact MathWorks support for installation help.

You should be asking your course instructor and TAs via the support forums in your course.
