How do I convert the frames/movie in this program to avi format so that I can show it in a power point presentation
y_max=50.0;
y_min=-50.0;
%F= (rand(20,10).*10);
N=300;
RandForce = 1030*rand(N,1) .* sign(randn(N,1));
k= 20.5;
y=RandForce./k;
%r=x_min+(x_max-x_min).*rand(n,1);
y(y_min > y | y > y_max) = 0;
figure(1)
plot(y); % Graphs the Plot
xlabel('frames');
ylabel('Random Positions');
figure (2)
scatter( 1:length(y), y, 90, [0 0 0], 'filled' );
xlabel('frames');
ylabel('Random Positions');
figure('Position', [300 300 300 300])
axlim=900;
aylim=80;
for i = 1:length(y)
%fprintf('Frame: %03d\n', i)
b=y;
plot(b,'.','MarkerSize',50)
axis([-axlim axlim -aylim aylim]);
% axis off
end
randommov = figure('Position', [300 300 300 300])
h=randommov;
set(h,'Position',[300 300 300 300])
set(h,'NextPlot','replacechildren')%Make sure each frame
%of the movie is the same size
axlim=900;
aylim=80;
N=10;
count=1;
M=moviein(N);
for j = 1:N
%fprintf('Frame: %03d\n', i)
b=y;
plot(b(j),'.','MarkerSize',50)
axis([-axlim axlim -aylim aylim]);
title('Microsphere');
S1=sprintf('Frame: %03d\n', j);
text(6,.5,S1)
titlestr = sprintf('Frame: %03d', k); % our title will change
%fprintf('Frame %d\n', k); % print loop counter68.
pause(0.1);
% axis off
M(:,j) = getframe(randommov);
M(count)=getframe(h);
count=count+1;
%movie(M)
end

If necessary if you have an older MATLAB, use avifile. However, it is better to use VideoWriter if you have it.
