 All operators act in a similar, intuitive way. There are many different kinds of objects which can be operated on. The list below gives the most general case wherever possible (i.e. does not distinguish [[IXTdataset_1d]] from [[IXTdataset_2d]]). Remember that the signal (and error) data in an [[IXTdataset_1d]] can be thought of as a single row of data, while the signal data in an [[IXTdataset_2d]] can be thought of as a matrix, with  x data corresponding to the columns and y data to the rows. Here '''bold''' represents an array, w an [[IXTdataset_1d]] and ww an [[IXTdataset_2d]].
