cartesian_to_spherical
(x, y, z)[source]¶ Converts 3D rectangular cartesian coordinates to spherical polar coordinates.
Note that the resulting angles are latitude/longitude or elevation/azimuthal form. I.e., the origin is along the equator rather than at the north pole.
Note
This function simply wraps functionality provided by the
CartesianRepresentation
andSphericalRepresentation
classes. In general, for both performance and readability, we suggest using these classes directly. But for situations where a quick oneoff conversion makes sense, this function is provided. Parameters
 xscalar, array_like, or
Quantity
The first Cartesian coordinate.
 yscalar, array_like, or
Quantity
The second Cartesian coordinate.
 zscalar, array_like, or
Quantity
The third Cartesian coordinate.
 xscalar, array_like, or
 Returns
 r
Quantity
The radial coordinate (in the same units as the inputs).
 lat
Quantity
[:ref: ‘angle’] The latitude in radians
 lon
Quantity
[:ref: ‘angle’] The longitude in radians
 r
