# FuzzyNumber: Creates a Fuzzy Number In FuzzyNumbers: Tools to Deal with Fuzzy Numbers

## Description

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

## Usage

 ``` 1 2 3 4 5 6 7 8 9 10``` ```FuzzyNumber( 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)) ) ```

## 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_
