[SOLVED] 3d cube with x,y,z directional vectors

[dwsmith]

How can I plot a 3d cube with x,y,z directional vectors going through it?

Mathematica or Matlab or Tikz package Latex

Do you still need help with this? There are many examples on the web. Do you need the origin to be in the center of the cube or in one of its vertices?

I don't need a x,y,z axis. A cube in free space only with vectors. I still need help.

This is one way.

 \usetikzlibrary{arrows}
 \begin{tikzpicture}[>=stealth',x=2cm,y=2cm,z=0.77cm]
 \fill (0,0) circle (1.5pt);
 \draw (0,0) -- (1,0) -- (1,1) -- (0,1) -- cycle;
 \begin{scope}[shift={(0,0,1)}]
 \draw (0,0) -- (1,0) -- (1,1) -- (0,1) -- cycle;
 \end{scope}
 \draw (0,0) -- (0,0,1) (0,1) -- (0,1,1) (1,0) -- (1,0,1) (1,1) -- (1,1,1);
 \end{tikzpicture}

For the description of the XYZ coordinate system, see section 22.2 on p. 249 in the v. 2.10 TikZ manual.
