# compass

## Purpose

Compass plot.

## Synopsis

    compass(z)
    compass(x,y)

## Description

`compass(z)` draws a graph that displays the angle and magnitude of the complex elements of `z` as arrows emanating from the origin.

`compass(x,y)` is equivalent to `compass(x+i*y)`. It displays the compass plot for the angles and magnitudes of the elements of matrices `x` and `y`.

## Examples

Draw a simple compass plot of the eigenvalues of a matrix:

    z = eig(randn(20,20))
    compass(z)
