simPYY1: PFS similarity measure simPYY1

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

PFS similarity measure simPYY1

Description

PFS similarity measure values using simPYY1 computation technique with membership, and non-membership values of two objects or set of objects.

Usage

simPYY1(ma, na, mb, nb, k)

Arguments

ma	PFS membership values for the data set x computed using either triangular or trapezoidal or guassian membership function
na	PFS non-membership values for the data set x computed using either Sugeno and Terano's or Yager's non-membership function
mb	PFS membership values for the data set y computed using either triangular or trapezoidal or guassian membership function
nb	PFS 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 PFS similarity values of data set y with data set x
