reduced_lat_from_geodetic_lat

Ellipsoid.reduced_lat_from_geodetic_lat(self, geodetic_lat: double | ndarray[double]) → double | ndarray[double]

Vectorized conversion from geodetic latitude \(\phi\) to reduced latitude \(\beta\).

Applies the element‐wise C routine to scalars or 1-D arrays of \(\phi\).

Parameters:

geodetic_latfloat or ndarray of float, shape (N,)

Geodetic latitude(s) \(\phi\) in radians.

Returns:

reduced_latfloat or ndarray of float, shape (N,)

Reduced latitude(s) \(\beta\) in radians.
