simHY4: IFS similarity measure simHY4

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

IFS similarity measure simHY4

Description

IFS similarity measure values using simHY4 computation technique with membership, and non-membership values of two objects or set of objects.

Usage

simHY4(ma, na, mb, nb, k)

Arguments

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

Value

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