+function [X, Y, Z] = geo2cart(phi, lambda, h, i)
+% GEO2CART Conversion of geographical coordinates (phi, lambda, h) to
+% Cartesian coordinates (X, Y, Z).
+%
+% [X, Y, Z] = geo2cart(phi, lambda, h, i);
+%
+% Format for phi and lambda: [degrees minutes seconds].
+% h, X, Y, and Z are in meters.
+%
+% Choices i of Reference Ellipsoid
+%   1. International Ellipsoid 1924
+%   2. International Ellipsoid 1967
+%   3. World Geodetic System 1972
+%   4. Geodetic Reference System 1980
+%   5. World Geodetic System 1984
+%
+%   Inputs:
+%       phi       - geocentric latitude (format [degrees minutes seconds])
+%       lambda    - geocentric longitude (format [degrees minutes seconds])
+%       h         - height
+%       i         - reference ellipsoid type
+%
+%   Outputs:
+%       X, Y, Z   - Cartesian coordinates (meters)
