520快到了，教你用matlab製作動態心形曲線表白（保存爲AVI視頻版本）

前面用matlab製作了gif的動態心形曲線：matlab製作動態心形曲線（保存爲gif版本）

% matlab動態心形曲線（AVI視頻版本）
clc;clear all;
a=0;
x=-2:0.01:2;
writerObj = VideoWriter('心形圖.avi');
writerObj.FrameRate = 20;
open(writerObj);
figure(1);
set(gcf,'position',[0,0,800,600],'color','w');
for i=1:200
    str_title = strcat('\color{red}a=',num2str(a));
    y = abs(x).^(2/3)+(0.9*sqrt((3.3-x.^2))).*sin(a*pi*x);
    a=i/10;
    figure(i);
    
    set(gcf,'position',[0,0,800,600],'color','w');
    p1 = plot(x,y,'r','LineWidth',3);
    hold on;
    title('\color{red}f(x)=x^2^/^3+e/3*(π-x^2)^1^/^2*sin(a*π*x)','fontsize',15);
    text(-0.2,2.3,str_title,'FontName','Times New Roman','FontSize',20);
    xlim([-2 2]);
    ylim([-1.5 2.5]);
    frame = getframe(gcf);
    writeVideo(writerObj,frame);
    close(figure(i));
    clf;
end
close(writerObj);

效果如下:
