Tools to Deal with Fuzzy Numbers

v0.4-7 · Nov 15, 2021 · LGPL (>= 3)

Description

S4 classes and methods to deal with fuzzy numbers. They allow for computing any arithmetic operations (e.g., by using the Zadeh extension principle), performing approximation of arbitrary fuzzy numbers by trapezoidal and piecewise linear ones, preparing plots for publications, computing possibility and necessity values for comparisons, etc.
