+% DESCRIPTION: Get the data property 'dx'.
+%
+% CALL:        val = dx(a1,a2,a3,...)
+%              val = dx(as)
+%              val = as.dx()
+%
+% INPUTS:      aN   - input analysis objects
+%              as   - input analysis objects array
+%
+% OUTPUTS:     val  - matrix with 'dx', one column for each input object
