%% Calculate the normal and tangential gravity with Exact method with other effects
% This example shows how to calculate the normal and tangential gravity at 1000 meters, 0 degrees latitude, and 20 degrees longitude and 11,000 meters, 30 degrees latitude, and 50 degrees longitude using the Exact method with atmosphere, centrifugal effects, and no precessing, with no actions for out-of-range inputs.

h = [1000; 11000];
lat = [0; 30];
lon = [20; 50];
[gn, gt] = gravitywgs84( h, lat, lon, 'Exact', 'None' )
