How do I open an m-file from the command line in the current instance of the Matlab editor?

If I run the following command at the dos prompt:

"C:\Program Files\MATLAB\R2011a\bin\matlab.exe" -r "edit('C:\Documents\MATLAB\test.m')"

a new instance of Matlab is opened with test.m open in the editor. Is there anyway to modify the command so that the m file is opened in the current instance of Matlab?

For context, I'm using TortoiseHg for source control in Windows. I'd like to be able to jump from a file listed in a revision history to viewing that file in Matlab. In THG, this is done by specifying a 'visual editor' as a command line specification.

Just use the function "edit". Try "help edit"

If you just want to use the editor, you can run "meditor test.m" at the command line.

meditor.exe is in folder matlabroot\bin\win32

I can't find meditor where you said it'd be -- it looks like Mathworks no longer includes it with Matlab?

I did manage to figure out that I can run "start test.m" at the command line to do what I want - this appears to be equivalent to double-clicking on a file in explorer and doesn't start a new matlab process unless necessary.

[Fangjun Jiang]

What version of MATLAB are you using? What happened if you run meditor at the dos prompt?

[Walter Roberson]

Newer versions do not include a stand alone editor.

I recall that there have been some previous Questions having to do with re-using the current instance of MATLAB under MS Windows. I did not pay attention to the details as I do not use MS Windows, but if you were to search MATLAB Answers for the word "instance" you would probably find the discussions.
