Convert between geodetic and isometric latitudes
IsometricLatitudeConverter object provides conversion
methods between geodetic and isometric latitudes for an ellipsoid with a given
The isometric latitude is a nonlinear function of the geodetic latitude that is
directly proportional to the spacing of parallels, relative to the Equator, in an
ellipsoidal Mercator projection. It is a dimensionless quantity and, unlike other types
of auxiliary latitude, the isometric latitude is not angle-valued. It equals
Inf at the north pole and
-Inf at the south
Eccentricity— Ellipsoid eccentricity
0| numeric scalar
Ellipsoid eccentricity, specified as a numeric scalar.
Eccentricity is in the interval [0, 0.5].
Eccentricities larger than 0.5 are possible in theory, but do not occur in
practice and are not supported.
