有MATLAB大神指导一下这张图怎么画么？
绘制爱心二维图，需要用这几个命令，如meshgrid，isosurface，isonormals，view等。具体实现过程如下：
[x,y,z]=meshgrid(linspace(-1.5,1.5));
val=(x.^2+(9/4)*y.^2+z.^2-1).^3-x.^2.*z.^3-(9/80)*y.^2.*z.^3;
[f,v]=isosurface(x,y,z,val,0);
p=patch('Faces',f,'Vertices',v,'CData',v(:,3),'FaceColor','w','EdgeColor','flat');
isonormals(x,y,z,val,p);
view(3);
axis equal
view([0 0]);
运行效果
