Transforms between angles in degrees and radians.
deg2rad(deg)
rad2deg(rad)
Arguments
- deg
(array of) angles in degrees.
- rad
(array of) angles in radians.
Details
This is a simple calculation back and forth. Note that angles greater than
360 degrees are allowed and will be returned. This may appear incorrect but
follows a corresponding discussion on Matlab Central.
Value
The angle in degrees or radians.

deg2rad(c(0, 10, 20, 30, 40, 50, 60, 70, 80, 90))
