This is a question which has been asked before, but to which I haven't been able to find a satisfactory response. I'm using Matlab R2016b on Linux, with a HiDPI screen (2560x1440) on a laptop - so a lot of pixels squeezed into a small space. And the standard menu fonts are tiny - so tiny that I have to squint carefully to read them.
I understand this to be in some way related to the Java system that Matlab uses for its GUI, but I have no idea how to increase the size of the menubar/toolbar fonts and icons. It's not included in Matlab's preferences; from my reading I believe that these are picked up somehow from the underlying OS. Or more accurately, from the underlying Java engine.
Currently, if I want to use Matlab with readable menus, I have to change my desktop resolution to a lower one, which of course affects every other application. So I'm hoping there's a better way?
