% DESCRIPTION: EXP overloads the exp operator for analysis objects. Exponential.
%              EXP(ao) is the exponential of the elements of ao.data
%                      e to the ao.data.
%
% CALL:        ao_out = exp(ao_in);
%              ao_out = exp(ao_in, pl);
%              ao_out = exp(ao1, pl1, ao_vector, ao_matrix, pl2);
%
% POSSIBLE VALUES: ao_in  = [ao2 ao3]
%                  ao_in  = ao_vector
%                  ao_in  = ao_matrix
