I am running R2019a in Ubuntu 18.04.
When I disable "Tab key inserts spaces" in the preferences, the editor successfully uses tabs instead of spaces. However, it fails to remember that I have done so the next time I start Matlab (this is a recurring problem for many things with Matlab in Ubuntu).
Can I set the "Tab key inserts spaces" to off from the Matlab command line? If so, then I can just paste that into my startup.m file and never have to worry about it again.
