In Rfmtool: Fuzzy Measure Tools

Function for checking if tuple B is subset of tuple A

Description

Checks if tuple B is a subset of tuple A, The cardinalities of both tuples need to be supplied.

Usage

  fm.is_subset_sparse(A, cardA, B, cardB, envsp = NULL)

Arguments

A	Tuple
cardA	Whose cardinality can be 1,2, other (automatically determined)
B	Tuple, tup=0
cardB	Whose cardinality can be 1,2, other (automatically determined)
envsp	Structure required for sparse representation which stores the relevant values (k-tuples). It is obtained from fm.PrepareSparseFM(n).

Value

output

The output is a logical value.

Examples

  n <- 3
  envsp <- fm.PrepareSparseFM(n, vector(), vector()) 
  envsp <- fm.add_singletons_sparse(c(0.2,0.1,0.2),envsp) 
  envsp <- fm.add_tuple_sparse(c(1,2,3),0.4,envsp);
  envsp <- fm.add_pair_sparse(1,2,0.2,envsp);

  fm.is_subset_sparse(0,3,0,2,envsp) #is 0th pair a subset of the 0th truple?
  fm.is_subset_sparse(0,3,1,2,envsp) #is 1th pair a subset of the 0th truple?

  envsp<-fm.FreeSparseFM(envsp)
