Matlab7 for Linux

[Rodolphe Conan]

Hello,

I am running FreeBSD 5.3 with linux_base-8 installed.
I have installed the linux version of Matlab 7 and now when I start
matlab I have this warning message:
/compat/linux/usr/local/Matlab/bin/matlab: line 1: /lib/libc.so.6:
cannot execute binary file
Any idea what does it mean?
It doesn't really prevent Matlab to work but I just cannot make 3D
surface plots. A simple mesh(zeros(20)) will run forever taken all my
cpu!!

Thanks for your help
Rod
