WebAn indicator function or a characteristic function of a subset A of a set S with the cardinality S = n is a function from S to the two elements set {0, 1}, denoted as IA: S → {0, 1}, and it indicates whether an element of S belongs to A or not; If x in S belongs to A, then IA ( x) = 1, and 0 otherwise. WebI know that Cardinality is the measurement of a set's size based on the number of elements in a system. I was wondering, to avoid any misinterpretation of the meaning behind what Cardinality is described, to be precise based on the term "Size", is it referring specifically to quantity, to like say measurements of an objects, both, more or none? thoriated lenses
