problem with freemat

chrischristian · 01-30-2009, 10:46 PM

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 ?

Well I am not quite sure of version, I netinst it and than I formated the PC now on laptop I'm running lenny , I downloaded a CD of it. I tried making a custom function just a simple one ...

t=(-pi,pi);
x=sin(t);

and then named it chris1 and added the folder in freemat path but, didn't work, still give UNDIFINED FUNCTION OR VARIABLE error, I have attched the edited path , directories not visible in attachments are ...

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.

I use lenny but I couldn't found that .conf file I tried apt-get purge freemat but even that has not removed freemat completely and on reinstall it comes with all that history and path, I find just tool box and binary in usr/local/share folders I REALLY NEED FREEMAT TO WORK URGENTLY AND DON'T WANT TO GIVE UP LINUX, HAVE TO HAVE A PRESENATATION ABOUT AMPLIFIER CALCULAIONS VERYSOON, I'M A NEWBI SO PLEASE HELP ME !!! THSNKS FOR REPLIES

cd into ~/.config/FreeMat

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'
....
