Yes.  I have to do the same thing in one of my SlackBuilds:
https://slackbuilds.org/slackbuilds/15.0/system/bat/bat.SlackBuild

There is no "install" target so I copy everything manually into $PKG.

I would suggest somewhere sensible that the user would have to manually add to the Matlab path.  If you're utilizing /opt then obviously a subdirectory there.  From browsing the FHS (https://refspecs.linuxfoundation.org/FHS_3.0/fhs/index.html) /usr/libexec/$PRGNAM would make the most sense to me, because from the point of view of Matlab, they are executable files.

Matlab by default adds $HOME/Documents/MATLAB to the Matlab path, but you can't install anything to $HOME in a package.

However, if the user needs read/write permission to the plugin directory, then I would argue for /usr/share/$PRGNAM and instruct the user to copy the files to their home directory before using.  Because in that case, the files belonging to the package are more similar to just data.

I would argue same as Matlab.
