Hello there!
So, the problem is: I'm trying to analyse how parameters of an offset parabolic antenna would change if it was made not as a paraboloid cut (smooth surface), but as an array of hexagonal facets of defined size (not smooth surface) and I need to export it as an STL, so i could "feed" it to my EM software. I have already created a code, that generates a mirror surface in polar coordinates and calculates angles between normal at every point on the surface and focus point.
I have two questions:
1) Is it even possible to accomplish what I need in Matlab?
2) If yes, then where do I even start?

1) yes
2) Look at stlwrite and triangulation.
