% DESCRIPTION: LOG overloads the log operator for analysis objects.
% Natural logarithm.
% LOG(ao) is the natural logarithm of the elements of ao.data.
%
% CALL: ao_out = log(ao_in);
% ao_out = log(ao_in, pl);
% ao_out = log(ao1, pl1, ao_vector, ao_matrix, pl2);
%
% PARAMETERS: see help for data2D/applymethod for additional parameters
