How to Plot Particles and Calculate Spherical Harmonics in MATLAB?

[JoAuSc]

I have data for the positions of particles in 3D space and I'm trying to use MATLAB in order to visualize it. How do I plot little balls in 3D? The only function I can find at the minute is streamParticles but I'm looking for something simpler.

EDIT: Nevermind, I figured it out. You simply do plot3(x,y,z,'.'), where x, y, and z are arrays of coordinates.


I do have another question, though. How do you find the spherical harmonics component of a point in MATLAB? In other words, if you have a set of points $$r_i$$, how would you find $$Y_l_m (r_i)$$?

You need to expand the points in a series of $$Y_l_m (r_i)$$. It is a fairly straightforward proceedure to do so.
