 PlotVector
 plots a Student[VectorCalculus] Vector object

 Calling Sequence PlotVector(v, opts)

Parameters

 v - Vector or list(Vector); specify which Vector(s) to plot opts - (optional) plot options

Description

 • The PlotVector(v) command takes a Vector or a list of Vectors, and plots them in the appropriate form:
 – Free Vectors and rooted Vectors are plotted using plots[arrow]. Rooted Vectors are positioned correctly.
 – Vector fields are plotted using plots[fieldplot] or plots[fieldplot3d]. If one or more ranges are missing in opts, a default range is applied.
 • If v is a Vector, the plot options given in opts will be passed on to the appropriate plot command.
 • If v is a list of Vectors, then the appropriate plotting command is invoked for each Vector in v with the plot options given in opts.
 – To visually distinguish these Vectors in the plot, the color plot option can be supplied as a list. If this is done, Vectors in v will be plotted using respective colors from this list. In particular, the color list and the list of Vectors v must have the same size.
 – Note that the color option can also be given as colour. For more information, please see plot/color and plot/colornames.
 • Use PlotPositionVector to plot position Vectors.
