MATLAB绘制GIF格式的动态曲线

代码如下：

clc;clear;close all;
fig=figure;
x=0:2*pi*0.01:2*pi;
im=cell(1,length(x));
for i = 1:length(x)
  y=sin(i*x/10);
  plot(x,y,'r')
  pause(0.5)
  drawnow
  frame = getframe(fig);
  im{i} = frame2im(frame);
end
filename = 'C:\Users\13349\Desktop\BILIBILI稿件\MATLAB动图\testAnimated.gif'; % Specify the output file name
for idx = 1:length(x)
  [A,map] = rgb2ind(im{idx},256);
  if idx == 1
    imwrite(A,map,filename,'gif','LoopCount',Inf,'DelayTime',1);
  else
    imwrite(A,map,filename,'gif','WriteMode','append','DelayTime',1);
  end
end
