Divergence Spherical Coordinates

This code takes an expression for a normalized AF in spherical coordinates and creates a 3D plot in cartesian coordinates. Examples are specific to Antenna Theory and Design (2nd Ed) by Stutzman and Thiele.

Easy-to-use 3D grapher that plots high quality graphs for 2D and 3D functions and coordinates tables. Graphing equations is as easy as typing them down. Graphs are beautifully rendered with gradual colors and lighting and reflection effects. Both cartesian and polar coordinates are supported as...

A few days ago I was in need of uniformly random points generation on the surface of sphere. I suddenly discovered that common parametrization with 2 angles is useless, it gathers too many points in the poles. At MathWorld you can find the complete demonstration, here the main lines:To pick a...
