plotting an ellipsoild with an equation that is not set equal to one variable

1 view (last 30 days)
I thought this would be simple and straight forward but i really don't have a clue here. I need to plot an Ellipsoid with the eqution:
1 = (x^2)/4 + (y^2)/9 + (z^2)
Thanks, any help would be great. will "mupad" be helpful here?

Did you look up ellipsoid in the help? When or if you do, you'll find your answer with very very slight modifications to their demo:
[x, y, z] = ellipsoid(0,0,0, 2,3,1, 30);
surfl(x, y, z)
colormap copper
axis equal

It's just an example and not related to the original question.
To plot this ellipsoid, the code should be
(Center: (0,0,0), Half-axis: (sqrt(4),sqrt(9),sqrt(1)) = (2,3,1))
[x, y, z] = ellipsoid(0,0,0, 2,3,1, 30);
surfl(x, y, z)
colormap copper
axis equal
