How to plot vectors in Mathematica

Question

I am trying to plot vectors in mathematica, some 2d and some 3d.

Is there a way to do this?

I Need the coordinate axes and an arrow head on a line basically.

Thanks, Blake

Answer 1

Here are some examples that I think are self-explanatory:

Graphics[{Arrow[{{0, 0}, {1, 1}}], Arrow[{{0, 0}, {-1, 1}}]}, Axes -> True]

Graphics3D[{Arrow[{{0, 0, 0}, {1, 1, 1}}], Arrow[{{0, 0, 0}, {-1, 1, -1}}]}, Axes -> True, Boxed -> False]

Answer 2

You should look at these built in plots:

StreamPlot and ListStreamPlot

StreamPlot[{-1 - x^2 + y, 1 + x - y^2}, {x, -3, 3}, {y, -3, 3}]

StreamDensityPlot and ListStreamDensityPlot

VectorPlot and ListVectorPlot
