Need program to graph a vector

[FocusedWolf]

I want a program to help me visualize 3d vectors, and planes if possible. I'm looking for something free and easy that let's me pan the 3d coordinate system around so i can see the vectors from different perspectives.

Also i got this program called MATLAB that my school gave me... does it do this?

MATLAB can certainly plot vector fields.

Read the help on, for example, the quiver plotting function.
