My MATLAB editor stopped working. I’m not able to open any file via UI

  • 0

My MATLAB editor stopped working. I’m not able to open any file via UI or command (edit file.m). It all started when I was editing a script using matlab-emacs.

I found a workaround to open files, but it is annoying. First, I need to click with the right button of the mouse in the file I want to open. Then, I select Compare against > Choose. Clicking in one of the line numbers in the left panel opens the MATLAB editor. Once I’m in the editor, I can open any other file by choosing File > Open as Text.... I also tried reinstalling MATLAB, but the problem remained.

I am using MATLAB R2011a and Ubuntu 11.10.

    I spent a big amount of time reinstalling it, when it was far more simple.

    1. Select File > Preferences...
    2. In Editor/Debugger, my editor was set as a blank Text editor, instead of MATLAB Editor.
    3. Just pick MATLAB Editor in the radio button.

    MATLAB Editor

    matlab-emacs extension probably changed my settings.
