Question

如何用matlab绘制x^2*z^3+9y^2*z^3 /80=(x^2+9y^2/4+z^2-1)^3的函数图像。（见图）

Answer 1

1. clear;clc;

2. t=linspace(-1.5,1.5);

3. [x,y,z]=meshgrid(t,t/2,t);

4. v=x.^2.*z.^3+9*y.^2.*z.^3 /80-(x.^2+9*y.^2/4+z.^2-1).^3;

5. isosurface(x,y,z,v,0,z);

6. axis equal

7. xlabel('x');ylabel('y');zlabel('z');

8. box on;grid on
