Catenate (The Index [I1 Entry Is an Integer): The catenate function joins two items along

an existing coordinate. (See the laminate function following for a description of how

to join two items along a new coordinate). The index [I], if given, specifies which

coordinate is expanded. The index entry must be a positive scalar or one-element

array. If no index [I] is specified, the last coordinate is used. Matrices of unequal

sizes can be joined, providing the lengths of the coordinate not specified are the

same (see Catenation in Chapter 3):
