Title: Tools to deal with fuzzy numbers in R
Description: The FuzzyNumbers package provides S4 classes and methods
to deal with Fuzzy Numbers. It allows for computations of
arithmetic operations on FNs, approximation by trapezoidal and
piecewise linear FNs, random FN generation, etc.

operations (e.g. by using the Zadeh extension principle),
perform approximation of arbitrary FNs by trapezoidal and piecewise
linear FNs, prepare plots of FNs for publications, etc.

Title: Apply Two Fuzzy Numbers on a Monotone Function
Description: One can easily draw the membership function of f(x,y) by package 'FuzzyNumbers.Ext.2' in which f(.,.) is supposed monotone and x and y are two fuzzy numbers. This work is possible using function f2apply() which is an extension of function fapply() from Package 'FuzzyNumbers' for two-variable monotone functions.
