uninstalling matlab

Halo,
I installed matlab 7 on my PC but now it's not getting uninstalled(I think some file is missing). I tried through control panel and revo uninstaller but to no avail. A DOS like window comes for 1ms and goes away instantly. So I need anyone to help me regarding this as it is making my system slow and I need to remove it as soon as possible. Also if anyone could give me link to any software which can uninstall it.
Please help me. I dont want matlab in my PC.

Thanks

Have you tried deleting the file it is stored in?

Which file are you talking about? I can't delete the matlab folder, it'll not fulfill my purpose of uninstalling it.
