Direction and Velocity Vector Graphs

Several MATLAB functions display data consisting of direction vectors and velocity vectors. This section describes these functions.

Function	Description
compass	Displays vectors emanating from the origin of a polar plot
feather	Displays vectors extending from equally spaced points along a horizontal line
quiver	Displays 2-D vectors specified by (u,v) components
quiver3	Displays 3-D vectors specified by (u,v,w) components

You can define the vectors using one or two arguments. The arguments specify the x and y components of the vectors relative to the origin.

If you specify two arguments, the first specifies the x components of the vectors and the second the y components of the vectors. If you specify one argument, the functions treat the elements as complex numbers. The real parts are the x components and the imaginary parts are the y components.
