请问谁能将这个matlab仿真动画保存为gif或者是avi格式啊?主程序已经编好了.主程序如下clear,rm=2;r=0.01:0.02:rm;th=linspace(0,2*pi,300);[R,TH]=meshgrid(r,th);[X,Y]=pol2cart(TH,R);eth=-3:0.3:3;rh=0.5:0.1:rm;phi=(0:10:350)*pi

rh=0.5:0.1:rm;phi=(0:10:350)*pi/180;
[RH,PHI]=meshgrid(rh,phi);
[XH,YH]=pol2cart(PHI,RH);
figure,fs=16;t=0;
while 1
if get(gcf,'CurrentCharacter')==char(27)return;end
Eth=cos(TH).*cos(2*pi*(t-R))./R;

可以先开一个视频写对象,
writerObj = VideoWriter('peaks.avi');
open(writerObj);
之后在循环里把每一帧加进去
frame = getframe;
writeVideo(writerObj,frame);
最后关闭
close(writerObj);
