Hello

I would like to add a directory with my private .m files permanently to
Matlab. 

    -  first I called pathtool added the path but then when I wanted to
       save it, matlab wanted to save the file, pathdef.m in the system
       directory /usr/local/matlab7 where I don't have write access and
       frankly I don't want to change that. So I saved the file in my
       home directory but, no surprise, next time when I started matlab,
       matlab ignored the file. 

    -  I presume I need to set a startup directory, but I don't know
       how. 

    -  of course I could either have the line 
addpath /home/oub/Matlab-files
in every of my scripts or have for each directory a startup.m file with
this line, but all that is cumbersome. 
I presume I should edit a system file but I rather would have advice
first.



Could somebody help please?

thanks

Hello Uwe,

ever tried adding 'export MATLABPATH=/home/oub/Matlab-files'
to your ~/.profile file?

After 10+ years of Matlab experience on HP-UX, Solaris, and Linux
I can tell you that you never ever should modify any file of the
Matlab installation in a multi-user environment.  My preferred
directory layout for Unix systems is

/opt/matlab-7.1         # vanilla Matlab installation
/usr/local/lib/matlab   # system-wide modifications
$HOME/lib/matlab        # per-user modifications

No, it did not work, but something similar in my .tcshrc file worked.

setenv MATLABPATH /home/oub/ALLES/Matlab-init

Thanks!!!!

well it is not really a multi-user system. It is a Linux Laptop, but
after also more than 10 years on IBM AIX and Solaris, I prefer the
strict division: user + sys adm and always hesitate to edit system
(conf) files and prefer to do it locally for the user.
