Question

我正在使用称为“动画线”的功能来创建一些动画功能。我想了解如何将函数另存为GIF以便在其他地方使用，例如微软幻灯片软件。我正在尝试使用gif function，但不能。谁能建议我如何实现它或如何正确使用gif函数？这里是一个简单的代码：

    numpoints = 100000; 
x = linspace(0,4*pi,numpoints); 
y = square(x); 
y2 = 3 +square(x+1);
figure 
h = animatedline('Color','b','LineWidth',2); 
h2 = animatedline('Color','r','LineWidth',2);
grid on;
axis([0,12,-3,+6]) 
for k = 1:numpoints 
  addpoints(h,x(k),y(k)) 
  addpoints(h2,x(k),y2(k)) 
  drawnow  


end

Answer 1

使用imwrite函数创建gif。

numpoints = 500; 
x = linspace(0,4*pi,numpoints); 
y = square(x); 
y2 = 3 +square(x+1);
f = figure 
h = animatedline('Color','b','LineWidth',2); 
h2 = animatedline('Color','r','LineWidth',2);
grid on;
axis([0,12,-3,+6]) 
for k = 1:numpoints 
  addpoints(h,x(k),y(k)) 
  addpoints(h2,x(k),y2(k)) 
  drawnow  

  % Capture the plot as an image 
  frame = getframe(f); 
  im = frame2im(frame); 
  [imind,cm] = rgb2ind(im,256); 
  % Write to the GIF File 
  if k == 1 
      imwrite(imind,cm,'test.gif','gif', 'Loopcount',inf); 
  else 
      imwrite(imind,cm,'test.gif','gif','WriteMode','append'); 
  end 
end

该gif保存到名为test.gif的文件中。
