freemat installation

[Pedro Almeidas]

Hello FreeBSD support.
I'm writting you  to have any information about FreeMat installation in PCBSD 9.0.
In fact, i recently begin to use PCBSD, but i've a lot of problems to understand all. 
Recently, i downloaded Freemat from http://sourceforge.net/projects/freemat/files/
them i donwnloaded -tar.gz- file extension. But, i don't know how to use this pack, install and run then in pcbsd.
I didn't found information in youtube.com, so, i'm writting you to know if you can inform me about steps to install it. 
Best Regards.
