matlab怎么保存gif图？

如图，这个程序在matlab中运行是动态的，怎么保存为gif图

Answer 1

使用如下代码：
clear
clc
close all
figure;
filename='trace.gif';
x=linspace(0,10*pi,2000);
y=cos(x);
z=sin(x);
for i=1:2000
plot3(x(i),y(i),z(i),'-bo');
pause(0.1);
hold on;

F=getframe(gcf);
im=frame2im(F);
[I,map]=rgb2ind(im,256);

k=i-0;
if k==1;
imwrite(I,map,filename,'gif','Loopcount',inf, 'DelayTime',0.03);
else
imwrite(I,map,filename,'gif','WriteMode','append', 'DelayTime',0.03);
end

end
