Description

Converts radians to degrees and vice versa.

Usage

deg2rad(d)

rad2deg(r)

Arguments

d

degrees

r

radians

Details

Since \pi\,\mathrm{rad}=180^{\circ}, degrees (d) can be converted to radians (r) using r=d\cdot{}\pi/180 and the conversion of radians to degrees is d=r\cdot{}180/\pi.
