function deg = rad2deg(rad)
% 
% RAD2DEG: Convert radians to degrees.
% 
% Calling Sequence:
% 
%   rad = rad2deg(deg);
% 
% INPUT:
% 
%   rad		: Angle in radians.
%
% OUTPUT:
%
%   deg		: Angle in degrees.
% 
% Description:
% 
%   Convenient utility function for converting radians to degrees, which are
%   often the required angular units for functions in the NURBS toolbox.
% 
% Examples:
% 
%   Convert 0.3 radians to degrees
% 
%   deg = rad2deg(0.3);
