在 MATLAB Online 中打开

    clearvars
    R = 1;
    xo = 10;
    yo = 20;
    zo = 30;
    num_angles = 3600;
    latitudes = -80:20:80; % latitudes in degrees
    theta = linspace(0,2*pi,num_angles)';
    % lat_angle = latitides*pi/180; 
    x = R * cosd(latitudes);
    z = R * sind(latitudes);
    X = cos(theta) * x + xo;
    Y = sin(theta) * x + yo;
    Z = repmat(z, size(X,1),1) + zo;
    clf
    plot3(X,Y,Z);
    axis equal
