Convert between geodetic and rectifying latitudes
RectifyingLatitudeConverter object provides conversion
methods between geodetic and rectifying latitudes for an ellipsoid with a given third
The rectifying latitude maps an ellipsoid (oblate spheroid) to a sphere while preserving the distances along the meridians. Rectifying latitudes are used when implementing map projections, such as Equidistant Cylindrical, that preserve such distances.
ThirdFlattening— Third flattening of an ellipsoid
Third flattening of an ellipsoid, specified as a numeric scalar.
ThirdFlattening is in the interval [0,
ecc2n(0.5)], or approximately [0, 0.071797]. (Flatter
spheroids are possible in theory, but do not occur in practice and are not
