Ok I'm trying to install MatLab 7.0 R14 on Tiger 10.4.2 , it is the student version and it is saying that I have to have X11 installed on my machine. But I installed X11. Isn't that what the XCode Developer tools are? I installed the XCode packages that were in my Application/Installers folder and figured I was good to go. I installed MatLab but it said it won't open until I install X11. Even though I have the developer folder in my root directory the MatLab program won't open (can't find it?). Help.
