Question

怎样用MATLAB画出x^2+y^2=4和x+z=2的相交图？顺便能把图贴出来吗？谢谢！

Answer 1

t=linspace(-2,2);
[x,y,z]=meshgrid(t,t,t+2);
v=x.^2+y.^2-4;
[X,Y]=meshgrid(t);
Z=2-X;
h=contourslice(x,y,z,v,X,Y,Z,[0 0]);
view(23,46);
hold on;
surf(X,Y,Z,0*X,'edgec','none','facecolor','b');
isosurface(x,y,z,v,0);
alpha .5;axis equal;camlight;lighting gouraud;
set(h,'edgecolor','y','edgelighting','none');
