%COSD   Cosine of argument in degrees.
%   COSD(X) is the cosine of the elements of X, expressed in degrees.
%   For odd integers n, cosd(n*90) is exactly zero, whereas cos(n*pi/2)
%   reflects the accuracy of the floating point value for pi.
%
%   Class support for input X:
%      float: double, single
