各位大神，麻烦问一下里面的三维图与二维图如何共用一个三维坐标轴，（二维图在底平面），谢谢啦
@[f = @(A,B,x) 1.*x.^3 + 0.5.*A.*x + B; % 函数表达式
[A,B,x] = meshgrid(-10:.10:10,-10:.10:10,-5:.10:5); % 画图范围
v = f(A,B,x);
h = patch(isosurface(A,B,x,v,0));
isonormals(A,B,x,v,h)
set(h,'FaceColor','r','EdgeColor','none');
xlabel('A');ylabel('B');zlabel('x');
alpha(1)
grid on; view([1,1,1]); axis equal; camlight; lighting gouraud
hold on
ezplot('8.*A^3+27.*B^2', [-10,10,-10,10,0,0]);
grid on
hold off
