[xNorth,yEast,zDown]
= geodetic2ned(lat,lon,h,lat0,lon0,h0,spheroid) transforms
point locations from geodetic coordinates (lat, lon, h)
to local, north-east-down (NED), Cartesian coordinates (xNorth, yEast, zDown),
given a local coordinate system defined by the geodetic coordinates
of its origin (lat0, lon0, h0).
The geodetic coordinates refer to the reference body specified by
the spheroid object, spheroid. Each coordinate
input argument must match the others in size or be scalar.

[___] = geodetic2ned(___,angleUnit) specifies
the unit of the latitude and longitude input arguments, lat, lon, lat0,
and lon0.

Geodetic latitudes of one or more points, specified as a scalar
value, vector, matrix, or N-D array. Values must be in units that
match the input argument angleUnit, if supplied,
and in degrees, otherwise.

Longitudes of one or more points, specified as a scalar value,
vector, matrix, or N-D array. Values must be in units that match the
input argument angleUnit, if supplied, and in
degrees, otherwise.

Ellipsoidal heights of one or more points, specified as a scalar
value, vector, matrix, or N-D array. Values must be in units that
match the LengthUnit property of the spheroid object.

Geodetic latitude of local origin (reference) point(s), specified
as a scalar value, vector, matrix, or N-D array. In many cases there
is one origin (reference) point, and the value of lat0 is
scalar, but it need not be. (It may refer to a moving platform, for
example). Values must be in units that match the input argument angleUnit,
if supplied, and in degrees, otherwise.

Longitude of local origin (reference) point(s), specified as
a scalar value, vector, matrix, or N-D array. In many cases there
is one origin (reference) point, and the value of lon0 is
scalar, but it need not be. (It may refer to a moving platform, for
example). Values must be in units that match the input argument angleUnit,
if supplied, and in degrees, otherwise.

Ellipsoidal height of local origin (reference) point(s), specified
as a scalar value, vector, matrix, or N-D array. In many cases there
is one origin (reference) point, and the value of h0 is
scalar, but it need not be. (It may refer to a moving platform, for
example). Units are determined by the LengthUnit property
of the spheroid input.

x-coordinates of one or more points in the local NED system,
returned as a scalar value, vector, matrix, or N-D array. Units are
determined by the LengthUnit property of the spheroid input.

y-coordinates of one or more points in the local NED system,
returned as a scalar value, vector, matrix, or N-D array. Units are
determined by the LengthUnit property of the spheroid input.

z-coordinates of one or more points in the local NED system,
returned as a scalar value, vector, matrix, or N-D array. Units are
determined by the LengthUnit property of the spheroid input.
