matlab参数方程画椭球theta=linspace(0,2*pi,1000)beta=linspace(0,pi,1000)x=4*sin(beta).*cos(theta);y=9*sin(beta).*sin(theta);z=ones(size(theta),size(theta)).*cos(beta);mesh(x,y,z)我的运行不出来怎么回事

[theta beta]=meshgrid(linspace(0,2*pi,1000),linspace(0,pi,1000));
x=4*sin(beta).*cos(theta);
y=9*sin(beta).*sin(theta);
z=cos(beta);
mesh(x,y,z)
