MATLAB: After solving and plotting a set of ODEs in 3d, how can I label a specific point (e.g (2,9,5))

labeling a point in a graphode45

[t,y] = ode45(@(t,y) Filename(t,y,d,m,p,w0),tspan,y0);
plot3(y(:,1),y(:,2),y(:,3),'-o');

hold on
scatter3(2,9,5, 'ro', 'lineWidth', 2, 'MarkerFaceColor', 'r')
hold off

What about this approach?

cla
[x,y,z] = meshgrid(linspace(0,6e5,30));
F = (z-x).^2+(x-y).^2+(y-z).^2-1210000000;
isosurface(x,y,z,F,0)

axis vis3d

Use the function form of hold() and pass the axes handle.

hold(handles.plot3D_axes,'on')
