simKKDKS: SFS similarity measure simKKDKS

In ipsfs: Intuitionistic, Pythagorean, and Spherical Fuzzy Similarity Measure

SFS similarity measure simKKDKS

Description

SFS similarity measure values using simKKDKS computation technique with membership,non-membership, and indeterminacy membership values of two objects or set of objects.

Usage

simKKDKS(ma, na, mb, nb, ia, ib, k)

Arguments

ma	SFS membership values for the data set x computed using either triangular or trapezoidal or guassian membership function
na	SFS non-membership values for the data set x computed using either Sugeno and Terano's or Yager's non-membership function
mb	SFS membership values for the data set y computed using either triangular or trapezoidal or guassian membership function
nb	SFS non-membership values for the data set y computed using either Sugeno and Terano's or Yager's non-membership function
ia	SFS indeterminacy membership values for the data set x
ib	SFS indeterminacy membership values for the data set y
k	A constant value, considered as 1

Value

The SFS similarity values of data set y with data set x
