vector plot software?
what free software there is for vector plotting in 3d, you know for linear algebra, i installed euler which i think works for that but it splash me in the terminal the error: " (euler:2004): Gdk-CRITICAL **: IA__gdk_char_width: assertion `font != NULL' failed

If it's only for *plotting*, then I think GNUplot is capable of this.
I never used this feature so I can't tell how exactly it works, but startpage is your friend.
GNUplot : "...The source code is copyrighted but freely distributed..." what is this... is not there a free software that do the same than gnuplot?
It is free, [0]. There are other free licenses that forbid making modified
sources, but allow distribution of unmodified source and patch or a
modified binary.
I don't know plotting software, I use them only via Maxima or Octave.
can i plot vectors in maxima or octave? i want to visualize vectors
You might want to look at Sage, a very good mathematical software. It is a collection of various free software packages and a python interface. There is a web interface called the notebook which works in any modern browser, such as Abrowser. It is all free software, except for a library called cephes under a questionable license. Luckily, this is only used on FreeBSD, not on GNU/Linux. (But I hope this is replaced in the future)
Only software in public domain isn't copyrighted. (And stuff in the public domain is non-free if the source is not available.)
The GNUplot license is called "free" by gnu.org.
What else can you want?
