以y=sin(x）为例，直接上代码：

% 创建一个x和y的数组
x = linspace(-0.25*pi, 2.0*pi, 100);
y = sin(2*x-pi)+2;
% 创建一个图形窗口
figure;
% 绘制曲线
plot(x,y);
axis([-0.23*pi 2.0*pi 1 3])
box off
grid off
% 创建一个动态曲线
h = animatedline('Color','b','LineStyle','-','LineWidth',3);
xticks([]);  % 清空 x 轴的刻度位置
xticklabels({});  % 将 x 轴的刻度标签设置为空
yticks([]);  % 清空 y 轴的刻度位置
yticklabels({});  % 将 y 轴的刻度标签设置为空
text(-0.35*pi,0.9,'0','FontWeight','normal','FontSize',15);
text(0.21*pi,0.9,'\pi/2','FontWeight','normal','FontSize',15);
text(0.745*pi,0.9,'\pi','FontWeight','normal','FontSize',15);
text(1.18*pi,0.9,'3\pi/2','FontWeight','normal','FontSize',15);
text(1.705*pi,0.9,'2\pi','FontWeight','normal','FontSize',15);
% 逐步将数据添加到动态曲线中
for i = 1:length(x)
    addpoints(h, x(i), y(i));
    drawnow;
    pause(0.05);
    % 将当前图像保存为GIF文件
    frame = getframe(gcf);
    im = frame2im(frame);
    [imind, cm] = rgb2ind(im, 256);
    if i == 1
        imwrite(imind, cm, 'sinx.gif', 'gif', 'Loopcount', inf, 'DelayTime', 0.05);
    else
        imwrite(imind, cm, 'sinx.gif', 'gif', 'WriteMode', 'append', 'DelayTime', 0.05);
    end
end

运行结果：
