COS overloads the cos operator for Analysis objects. Cosine of argument in radians. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% DESCRIPTION: COS overloads the cos operator for Analysis objects. Cosine of argument in radians. COS(ao) is the cosine of the elements of ao.data.
