Vector Fields

Quiver, compass, feather, and stream plots

Vector fields can model velocity, magnetic force, fluid motion, and gradients. Visualize vector fields in a 2-D or 3-D view using thequiver,quiver3, andstreamlinefunctions. You can also display vectors along a horizontal axis or from the origin.
