How can I represent the ellipsoid?

To represent graphically the surface z (x, y), of the ellipsoid represented by the equation x ^ 2/36 + y ^ 2/25 + z ^ 2/9 = 100 with x [-2,2] and y [-4, 4]. Draw the contour lines, both drawings being represented horizontally in a single figure.

Hint: the expression for z in the equation represents the surface.

Anyone please? I'm a beginner. Thanks!

Matlab has a couple of functions which might help you:

Check

help contour

help contour3

especially the Live Scripts for ideas on how to approach your problem.

You may also want to consult

help meshgrid

to generate the X and Y variables for your specific problem when you're ready to try it.
