c_geodetic_lat_from_reduced_lat#

double Ellipsoid.c_geodetic_lat_from_reduced_lat(double reduced_lat)#

Compute the geodetic latitude \(\phi\) from a reduced (parametric) latitude \(\beta\).

\[\phi = \arctan\!\Bigl(\frac{\tan\beta}{1 - f}\Bigr)\]

All angles are in radians (SI).

param reduced_lat:

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

returns:

Geodetic latitude \(\phi\) in radians.

rtype:

float
