Mixed function

A mixed function is one of a class of primitive functions that consider their entire arguments rather than treating each element at a time. The exact parts of an argument that is considered as a unit, varies per function, rather than adhering to a general rule. Hence the name "mixed" as in a "mixed bag" of functions. This is opposed to scalar functions which are defined in terms of operations on simple scalars.

For example, while Equal is a scalar function in that it compares (corresponding) elements, Match  gives a single result which indicates if the arguments, as wholes, are identical.
