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

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

actually i didn't even think of doing that. I am looking at it now thanks.

How did you come up with the 30 for n?

That was just right from the example. Play around with it to get a value that you like.

hello. i would like to know how did you get the value that is stated in the bracket?

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
