% DESCRIPTION: APPLYMETHOD to the analysis object
%              Private static AO function that applies the given method to
%              the given AOs. This is called by all the simple methods like
%              abs, mean, acos, etc.
%
% CALL:        as = applymethod(copyObjects, callerIsMethod, in_names, operatorName, dxFcn, getInfo, getDefaultPlist, varargin)
