problem with freemat


Hi there,
I tried freemat with Windows and Debian etch erlier and in both for path setting I just included all the directories and folders related to freemat and it worked fine, but I have lenny on my laptop and freemat gives ERROR undifined function or variable even with basic function such as comb(3,7)??
Am I missing anything to include in path ??

Are you quite certain on this expression ??

I do not see it working on any OS.

Which version of FreeMat did you use on Etch ?

If you want an answer for your post marked # 4 :

1) Send an email to one of the other "FreeMat users"
e.g. GTrax
http://www.linuxquestions.org/questi...t4-rcc-698965/

1a) Use " LQ Search " to find more
http://www.linuxquestions.org/questions/search.php
or
2) Start a new thread with the new question and
keep it in " zero reply " for a couple of weeks :

Please do not answer your own question, like you
did here in # 2 !

( Makes the thread more invisible )

Good luck.

I don't think you want all the toolbox files in your path, rather they are referenced by "root=/usr/share/freemat/" in your ~/.config/FreeMat/FreeMat.conf. The best way to set this on a new installation is
Code:
FreeMat -i /usr/share/freemat/
Unless you want to retain some old command history info, I recommend wiping that FreeMat.conf file and start fresh.

Verify the exact path for your distribution - mine is in /usr/local/share, for example.

Can you please tell me where to find Freemat.conf ? cd into ~/.config/FreeMat gives nothing ??

What about this I find on this site

Note that a package should not modify a dpkg-handled conffile in its maintainer scripts. Doing this will lead to dpkg giving the user confusing and possibly dangerous options for conffile update when the package is upgraded.

But, of course, if you run 'freemat' as root ( which you should never do ),

Works for me in Lenny.
Please also try cd /home/chrischristian/.config/FreeMat
and next 'mc' to see the file FreeMat.conf .
Or just do 'mc' in your /home/"user" to see .config.

( mc is the Midnight Commander, a small file manager )

The history, you mention repeated, should be in FreeMat.conf only.
( Which you should be able to watch in your default file manager,
using the option 'Show hidden files'. )
....
EDIT ... try this one too : 'ls -aR | grep FreeMat.conf'
....
