I suppose it is because I have a free license (that runs until the end of September). However, even with a free license, I cannot install MATLAB since my company forbids it.
MATLAB Home is the new landing page for MATLAB and Simulink. Think of this page as more of a portal to all MathWorks products. From this page you can access help, the community pages (like this one), training courses, download MATLAB to install on your local computer, and access MATLAB Online if your license includes it.
It may be that your license does not include access to MATLAB Online. Do you know what type of license you have?
MathWorks does provide free licenses to courses through its MOOC support program. These free licenses only provide access to what is needed to complete the course.
Where possible, MATLAB Online is preferred. However, if the course you are taking is providing a desktop license, it is because at least some aspects of that course cannot yet be completed in MATLAB Online.
Which course is this? It must not be one of the courses in the Practical Data Science with MATLAB specialization, which you can also enroll in for free on Coursera, since they all use MATLAB Online.
