In the distribution, minor (minor) updates (bug fixes) for different versions of matlab and the main (major) version, they do not change. It is not necessary to download the entire distribution, you can select only the updates / platforms you need (although, of course, support for the distribution by seeding its entire volume is highly welcomed). Updates are cumulative - you can immediately install the desired version of the update without installing the previous ones (if there are any at all in the distribution). For example, immediately install 9.11 R2021b Update2 without installing 9.11 R2021b Update1.


How to install see the corresponding pdf-documentation. I have not checked the installation of all versions under all platforms ... too time consuming ... so feel free to unsubscribe about problems (including solutions found).
See the distribution pdfs for what each update adds.
Changing the set of Matlab components using its base installer already AFTER installing the updates is not officially supported. Officially, it is necessary to bang the matlab, re-install the matlab with an updated set of components, roll updates.
But this path can be shortened. To do this, replace the file \ VersionInfo.xml with the file of the same name from the distribution, then you need to install the components you need using the basic installer, and of course, at the end, re-roll the update you need

So far, updates to the Matlab are being successfully installed from the Internet (through the Matlab interface Home -> Help -> Check for Updates ). Getting offline updates - mafworks noticeably complicated (if you have them, share the balls / links in a personal or something else). For whom updating from servers is NOT "potential pale" ... try to update online (the latest released update is Update 1 )

When installing an update for Windows, you must first mount the corresponding iso file into the virtual drive, and then install it by running / bin / /update_installer.exe -updatepackage "". Under other operating systems, in general, it is similar. Read more in the file Matlab_UpdatesInstallInstructions.pdf or HERE (except that under Linux it is necessary to run "./update_installer.sh" instead of the specified "./update_installer" ... although you yourself will figure it out )


Simplification for Windows
Under Windows, you may find it more convenient to use the Update.cmd auxiliary file on the disk mounted from the iso file.
At the same time, if your matlab is installed in the default folder (i.e. in C: \ Program Files \ MATLAB \ R2021b), then you can simply run Update.cmd as Administrator and that's it.
If the matlab is not installed in the default folder, then you need to somehow explain Update.cmd where you have the matlab. To do this:
1. You can either pass the folder as the first parameter when launching Update.cmd ... ie. run a command like: Update.cmd "C: \ Math \ Matlab \ 911"
2. Or create an environment variable named FOLDER_MATLAB911 showing where you placed the 9.11 matlab (well, that is, let's say set it to C: \ Math \ Matlab \ 911) ... and then, as usual, run Update.cmd on behalf of the Administrator
