[Matlab-emacs-discuss] annoying path behavior of the *MATLAB* shell buffer who is the culprit

[Uwe B. <ou...@ma...>]

Hi all

I find the following quite annoying and look desperately for a solution.

I am using the following structure

Dir-Matlab/dir1/test.m
Dir-Matlab/dir2/test2.m

Now I open test.m and  run matlab-shell-save-and-go 
I see
>> cd(['/home/oub/ALLES/Dir-Matlab/dir1/'])
>> test 
y =    64

Which is ok, so I open test2.m in dir2 and do the same, again the shall
does it nicely 
>> cd(['/home/oub/ALLES/Dir-Matlab/dir2/'])
>> test2 
y =     49

And indeed
>> pwd

tells me 

/home/oub/ALLES/Dir-Matlab/dir2

Which is ok.

However when I use find-file, in the *MATLAB* shell, then the buffer of
the matlab shell thinks that I am still in dir1.

Find file: ~/ALLES/Dir-Matlab/dir1/

How can I tell the buffer that I am running that I am in the dir2?

Or in other words 
>> cd(['/home/oub/ALLES/Dir-Matlab/dir2/'])

should be reflected in the *MATLAB* buffer

Anybody has an idea how to achieve that?

The only idea which occurred to me is this function

(defun my-matlab-switch-and-save-default-directory ()
    (interactive)
    (let ((saved-default-directory default-directory))
	(switch-to-buffer "*MATLAB*")
                (setq default-directory saved-default-directory)))

Which should somehow be included in matlab-shell-save-and-go, any
suggestions?
