Which utilizes the following circles function:

function [ h ] = circles(x,y,r,varargin)
% h = circles(x,y,r,varargin) plots circles of radius r at points x and y.
% x, y, and r can be scalars or N-D arrays.

%% Syntax
%  circles(x,y,r)
%  circles(...,'points',numberOfPoints)
%  circles(...,'rotation',degreesRotation)
%  circles(...,'ColorProperty',ColorValue)
%  circles(...,'LineProperty',LineValue)
%  h = circles(...)
%
%% Description
%
% circles(x,y,r) plots circle(s) of radius or radii r centered at points given by
% x and y.  Inputs x, y, and r may be any combination of scalar,
% vector, or 2D matrix, but dimensions of all nonscalar inputs must agree.
%
% circles(...,'points',numberOfPoints) allows specification of how many points to use
% for the outline of each circle. Default value is 1000, but this may be
% increased to increase plotting resolution.  Or you may specify a small
% number (e.g. 4 to plot a square, 5 to plot a pentagon, etc.).
%
% circles(...,'rotation',degreesRotation) rotates the shape by a given
% degreesRotation, which can be a scalar or a matrix. This is useless for
% circles, but may be desired for polygons with a discernible number of corner points.
%
% circles(...,'ColorProperty',ColorValue) allows declaration of
% 'facecolor' or 'facealpha'
% as name-value pairs. Try declaring any fill property as name-value pairs.
%
% circles(...,'LineProperty',LineValue) allows declaration of 'edgecolor',
% 'linewidth', etc.
%
% h = circles(...) returns the handle(s) h of the plotted object(s).
%

%% EXAMPLES:
%
% Example 1:
% circles(5,10,3)
%
% % Example 2:
% x = 2:7;
% y = [5,15,12,25,3,18];
% r = [3 4 5 5 7 3];
% figure
% circles(x,y,r)
%
% % Example 3:
% figure
% circles(1:10,5,2)
%
% % Example 4:
% figure
% circles(5,15,1:5,'facecolor','none')
%
% % Example 5:
% figure
% circles(5,10,3,'facecolor','green')
%
% % Example 6:
% figure
% h = circles(5,10,3,'edgecolor',[.5 .2 .9])
%
% % Example 7:
% lat = repmat((10:-1:1)',1,10);
% lon = repmat(1:10,10,1);
% r = .4;
% figure
% h1 = circles(lon,lat,r,'linewidth',4,'edgecolor','m','facecolor',[.6 .4 .8]);
% hold on;
% h2 = circles(1:.5:10,((1:.5:10).^2)/10,.12,'edgecolor','k','facecolor','none');
% axis equal
%
% % Example 8: Circles have corners
% This script approximates circles with 1000 points. If all those points
% are too complex for your Pentium-II, you can reduce the number of points
% used to make each circle.  If 1000 points is not high enough resolution,
% you can increase the number of points.  Or if you'd like to draw
% triangles or squares, or pentagons, you can significantly reduce the
% number of points. Let's try drawing a stop sign:
%
% figure
% h = circles(1,1,10,'points',8,'color','red');
% axis equal
% % and we see that our stop sign needs to be rotated a little bit, so we'll
% % delete the one we drew and try again:
% delete(h)
% h = circles(1,1,10,'points',8,'color','red','rot',45/2);
% text(1,1,'STOP','fontname','helvetica CY',...
%     'horizontalalignment','center','fontsize',140,...
%     'color','w','fontweight','bold')
%
% figure
% circles([1 3 5],2,1,'points',4,'rot',[0 45 35])
%
%
% TIPS:
% 1. Include the name-value pair 'facecolor','none' to draw outlines
% (non-filled) circles.
%
% 2. Follow the circles command with axis equal to fix distorted circles.

but am getting the error: Error using movie

Movie contains uninitialized frames

1. How can I make this a movie?
2. How can I simply then save this movie as a .avi, .mp4, or whatever video format?

Thank you

Zach(i,size(r,2)) = getframe;

You are creating a 2d array of frames in which you assign into the last column. The other columns will be frame structures with no data. But you try to movie() the entire 2d array of structures.
