km = rad2km(rad)
converts distances from radians to kilometers, as measured along a great circle on a
sphere with a radius of 6371 km, the mean radius of the Earth.
km = rad2km(rad,radius)
converts distances from radians to kilometers, as measured along a great circle on a
sphere having the specified radius.
km = rad2km(rad,sphere)
converts distances from radians to kilometers, as measured along a great circle on a
sphere approximating an object in the Solar System.
Find the circumference of the Earth in kilometers. By default, the rad2km function assumes your input is a measurement of the Earth, which is represented as sphere with a radius of 6371 kilometers.
Distance in radians, specified as a numeric array.
Data Types: single | double
Radius of sphere in units of kilometers, specified as a numeric scalar.
Sphere approximating an object in the Solar System, specified as one of the following
values: 'sun', 'moon',
'mercury', 'venus',
'earth', 'mars', 'jupiter',
'saturn', 'uranus',
'neptune', or 'pluto'. The value of
sphere is case-insensitive.
