Use matlab to draw a beating heart

1. Open the MATLAB software, as shown in the figure:

2. Create a new script and copy the following program into the script . As shown in the picture:

clc,clear;
figure('Color','y')
while 1
for i=-5:0.2:5
f=@(xx,yy,zz) xx.^2.*zz.^3+9*yy.^2.*zz.^3/80-(xx.^2+9*yy.^2/4+zz.^2-1).^3;%心形曲面函数
[xx,yy,zz]=meshgrid(-1.5:0.1:1.5);%画图范围
vv=f(xx,yy,zz);
h=patch(isosurface(xx,yy,zz,vv,0));
isonormals(xx,yy,zz,vv,h)
set(h,'FaceColor','r','EdgeColor','none');
lighting gouraud
view(40*i,20)
drawnow 
axis equal off
grid off
pause(0.01)
end
end

3. Click Run to get a three-dimensional dynamic "heartbeat" that you can't imagine. It can be moved. Try it yourself. Programming can exercise your logical thinking ability and Spatial imagination ability, so I hope everyone can learn more knowledge through this small program, as shown in the picture:
