Retain current plot when adding new plots

N=100;
M=100;
R=10;
X=zeros(N+1,M+1);
X0=zeros(N+1,M+1)-R*2;
Y=zeros(N+1,M+1);
Y0=zeros(N+1,M+1)+R*2;
Z=zeros(N+1,M+1);
Z0=zeros(N+1,M+1)-R*2;
for i=1:N+1
    for j=1:M+1
        X(i,j)=R*sin(pi/(N-1)*i)*cos(2*pi/M*j);
        Y(i,j)=R*sin(pi/(N-1)*i)*sin(2*pi/M*j);
        Z(i,j)=R*cos(pi/(N-1)*i);
    end
end
hold off;
mesh(X,Y,Z);
hold on;
mesh(X,Y,Z0);
mesh(X,Y0,Z);
mesh(X0,Y,Z);

看个例子，你体会下，要投影要哪个面，就把那个面的坐标改成0，然后平移图像

N=100;
M=100;
R=10;
X=zeros(N+1,M+1);
X0=zeros(N+1,M+1)-R*2;
Y=zeros(N+1,M+1);
Y0=zeros(N+1,M+1)+R*2;
Z=zeros(N+1,M+1 ...

如果我要的不是投影，而是某个投影面的轮廓能做到吗
