Abstract. Index Matrices (IMs) are extensions of the ordinary matrices. Some of the operations and relations
defined over IMs are analogous of the standard ones, while there have been defined new ones, as well. Operators
that do not have analogues in matrix theory have been defined, as well. In general, the elements of an IM can be
real or complex numbers, as well as propositions or predicates. In the present paper, new operation over IMs with
elements being functions, is defined, and some of its properties are discussed.
Keywords: Function, Index matrix, Operation, Operator, Relation.
