Returns the parameters of the wgs84 ellipsoid. Argument unit is optional and if given, should be one of the units recognized by function validateLengthUnit().
Example:
>> E = wgs84Ellipsoid E = scalar structure containing the fields: Code = 7030 Name = World Geodetic System 1984 LengthUnit = meter SemimajorAxis = 6378137 SemiminorAxis = 6.3568e+06 InverseFlattening = 298.26 Eccentricity = 0.081819 Flattening = 0.0033528 ThirdFlattening = 0.0016792 MeanRadius = 6.3710e+06 SurfaceArea = 5.1007e+14 Volume = 1.0832e+21
A unit argument is also accepted:
>> E = wgs84Ellipsoid ("km") E = scalar structure containing the fields: Code = 7030 Name = World Geodetic System 1984 LengthUnit = km SemimajorAxis = 6378.1 SemiminorAxis = 6356.8 InverseFlattening = 298.26 Eccentricity = 0.081819 Flattening = 0.0033528 ThirdFlattening = 0.0016792 MeanRadius = 6371.0 SurfaceArea = 5.1007e+08 Volume = 1.0832e+12
