Hello,
I have generated this 3D dome surface using MATLAB using the SURF command. I need to find the height (Z) of the dome at parts other than center (Like for example at (X=-2000, Y=-2000, Z=?)). How can I achieve that using MATLAB? see the image attached below for reference.
Hi Usman,
If your dome is generated using the equation of sphere,
x2 + y2 + z2 = 30002
then the height of the dome at any part can be determined by
z = √ {30002 − x2 − y2}.
For example, given x = −2000 and y = −2000, then
z = √{1,000,000} = 1000.

Following Yew-Chung Chak's answer, according to Matlab's documentation, https://uk.mathworks.com/help/matlab/ref/surf.html surf takes X, Y, Z arguments to create a surface. The function you use to define/calculate Z will give you the z-co-ordinate, or the height (regardless as to whether the dome is a spherical dome or not). Simply substitute in your X and Y co-ordinates.
