cartesian_to_poincare_polar¶

gala.coordinates.cartesian_to_poincare_polar(w)[source]¶

Convert an array of 6D Cartesian positions to Poincaré symplectic polar coordinates. These are similar to cylindrical coordinates.

Parameters:	w : array_like Input array of 6D Cartesian phase-space positions. Should have shape `(norbits,6)`.
Returns:	new_w : `ndarray` Points represented in 6D Poincaré polar coordinates.
