compass

Compass plot — vectors radiating from origin.

Syntax

h = compass(u, v, ...)
h = compass(z, ...)

Description

Draws arrows from the origin to each (u, v) point (or to each complex z). Useful for visualizing direction-and-magnitude data on a circular axis.

Example

compass([1 0 -1 0], [0 1 0 -1])    % four cardinal directions
