I am using Matlab R2013b. I am using the GUI, with the Command Windows and Editor in split screen. In the Matlab preferences > Editor/Debugger > Editor. There is an option to set a custom editor instead of the Matlab editor. I set it to my local editor `/usr/bin/vim`, but then I am not able to open files at all anymore. Is there a possibility to use the `vim` editor in split screen mode?

I am aware of `!vim file.m`, but this is not the solution I am looking for, as this only works satisfactory in `-nodisplay` mode. I rather want to keep the split screen mode.
