TITLE: How to plot vectors in Mathematica
QUESTION [14 upvotes]: 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

REPLY [4 votes]: 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


VectorPlot3D and ListVectorPlot3D
