Increase font size of matlab editor

Hi all,

I am running Matlab on a university server on my Laptop Lenovo ThinkPad X1 Carbon (OS Debian 8.7 Jessie) and GNOME Shell 3.14.4 as desktop Environment. As you can see from the attached screenshot the fond of the Matlab editor is anyway too small to comfortably work with. I tried to modify the font size using the settings menu but I haven't found any option related to that. May you kindly help me please?

Thanks in advance
