DiscontinuousFuzzyNumber

Creates a Fuzzy Number with Possibly Discontinuous Side Functions or Alpha-Cut Bounds

Description

For convenience, objects of class DiscontinuousFuzzyNumber may be created with this function.

Usage

DiscontinuousFuzzyNumber(a1, a2, a3, a4, lower = function(a)
  rep(NA_real_, length(a)), upper = function(a) rep(NA_real_, length(a)),
  left = function(x) rep(NA_real_, length(x)), right = function(x)
  rep(NA_real_, length(x)), discontinuities.left = numeric(0),
  discontinuities.right = numeric(0),
  discontinuities.lower = numeric(0),
  discontinuities.upper = numeric(0))

Arguments

`a1`	a number specyfing left bound of the support
`a2`	a number specyfing left bound of the core
`a3`	a number specyfing right bound of the core
`a4`	a number specyfing right bound of the support
`lower`	lower alpha-cut bound generator; a nondecreasing function [0,1]->[0,1] or returning NA_real_
`upper`	upper alpha-cut bound generator; a nonincreasing function [0,1]->[1,0] or returning NA_real_
`left`	lower side function generator; a nondecreasing function [0,1]->[0,1] or returning NA_real_
`right`	upper side function generator; a nonincreasing function [0,1]->[1,0] or returning NA_real_
`discontinuities.left`	nondecreasingly sorted numeric vector with elements in (0,1), possibly of length 0
`discontinuities.right`	nondecreasingly sorted numeric vector with elements in (0,1), possibly of length 0
`discontinuities.lower`	nondecreasingly sorted numeric vector with elements in (0,1), possibly of length 0
`discontinuities.upper`	nondecreasingly sorted numeric vector with elements in (0,1), possibly of length 0

Value

Object of class DiscontinuousFuzzyNumber
