Command history file not being saved/loaded on Ubuntu

Hi,

I am running R2011A on Ubuntu. The history.m file saved commands from first ever session that I ran. After that it stopped updating it, and every session would load commands from that first session. I tried (backing up first and then) deleting the history file, but it would not create a new history.m file in my PREFDIR. So at the startup, the command history window is empty. Even after I manually created a history.m file, it wouldn't save anything in it. It doesn't give any error so I don't know if it is trying to save but cannot. Here are the permissions in my PREFDIR

drwxr-xr-x 2 ab ab 4096 2011-08-11 17:41 .

drwxr-xr-x 3 ab ab 4096 2011-07-07 12:55 ..

Would appreciate any insights. Thanks! Ab

Fixed: After I changed the permissions and added the .prf file to be used by user.

sudo chown -R ${USER}:${USER} ~/.matlab

And then rebooted the machine and the changes took place. Now my history loads just fine since yesterday.
