+% SIN overloads the sin method for analysis objects.
+%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
+%
+% DESCRIPTION: SIN overloads the sin operator for analysis objects.
+%
+% CALL:        ao_out = sin(ao_in);
+%              ao_out = sin(ao_in, pl);
+%              ao_out = sin(ao1, pl1, ao_vector, ao_matrix, pl2);
+%
+% POSSIBLE VALUES: ao_in  = [ao2 ao3]
+%                  ao_in  = ao_vector
+%                  ao_in  = ao_matrix
