# comet3

## Purpose

Three-dimensional comet plot.

## Synopsis

    comet3(z)
    comet3(x,y,z)
    comet3(x,y,z,p)
    comet

## Description

A comet plot is an animated graph in which a circle (the comet head) traces the data points on the screen. A trailing segment, the comet body, follows the head. The tail traces the entire function using a solid line.

`comet3(z)` displays an animated, three-dimensional comet plot of the vector `z`.

`comet3(x,y,z)` displays an animated comet plot of the curve through the points `[x(i),y(i),z(i)]`.

`comet3(x,y,z,p)` uses a comet body of length `p*length(y)`. The default value for `p` is 0.1.

`comet3`, with no arguments, provides a demonstration of the three-dimensional comet plot.

## Examples

    t = -10*pi:pi/250:10*pi;
    comet3((cos(2*t).^2).*sin(t),(sin(2*t).^2).*cos(t),t)
