If ./install exists in your current directory, and you are using Linux, but sudo ./install says that the command is not found, then you might be accessing a filesystem that has the no-execute flag set. In that case you can try
sudo sh ./install

Could still be -noexec problem or needs
sudo chmod -r ugo+x .
The final period is part of the command

Dear Mr. @Walter Roberson, I am very grateful for your time and help. It seems like the problem was from the way I extracted the installation files from the MATLAB ISO file downloaded online. I had to mount the iso file following the steps in this link.

Then, I activated the installed Matlab following this link
https://www.mathworks.com/matlabcentral/answers/99457-how-do-i-activate-matlab-or-other-mathworks-products
It took me almost three days. I will now proceed with installing other tools and packages.
I am sharing this in case it might help others.
Regards,
