I have an R2018b version in my PC and now I want to install 2019a. What should I do? Must I uninstall 2018b and then install 2019a? Or can I update directly?

You should just be able to go to the downloads page of the MathWorks site.

You do not need to uninstall your old version. (You can keep mulitple versions on your machine.)

the cyclist is right, but one point I want to add: install the new version in a new directory.

Don't try to install two releases in the same directory, as that could lead to using the wrong function (if a function is changed and moved to a different directory in the newer release, whether its new home or its old home is first on the MATLAB path would impact whether the new version or the old version gets called.)
