rad2sm

Convert spherical distance from radians to statute miles

Syntax

sm = rad2sm(rad)

sm = rad2sm(rad,radius)

sm = rad2sm(rad,sphere)

Description

sm = rad2sm(rad) converts distances from radians to statute miles, as measured along a great circle on a sphere with a radius of 3958.748 sm, the mean radius of the Earth.

sm = rad2sm(rad,radius) converts distances from radians to statute miles, as measured along a great circle on a sphere having the specified radius.

sm = rad2sm(rad,sphere) converts distances from radians to statute miles, as measured along a great circle on a sphere approximating an object in the Solar System.

Examples

Convert Arc Length to Statute Miles

How long is a trip around the equator in statute miles?

sm = rad2sm(2*pi)

sm = 2.4874e+04

How about on Jupiter?

sm = rad2sm(2*pi,'jupiter')

sm = 2.7283e+05

Input Arguments

rad — Distance in radians

numeric array

Distance in radians, specified as a numeric array.

Data Types: single | double

radius — Radius

3958.748 (default) | numeric scalar

Radius of sphere in units of statute miles, specified as a numeric scalar.

sphere — Sphere

'sun' | 'moon' | 'mercury' | 'venus' | 'earth' | ...

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.
