Function checking [FuzzyStatTra v1.0]
keywords
attribute
title
description
The function checks if the input data are given in the correct form of an array of dimension nl x 3 x n containing n fuzzy numbers characterized by means of nl \(\alpha\)-levels each. The following conditions have to be fulfilled: (1) the number of columns of the array must be 3 (the first column will be the \(\alpha\)-levels, the second one their infimum values and the third one their supremum values), (2) all the fuzzy numbers must have the same column of \(\alpha\)-levels, (3) the minimum \(\alpha\)-level should be 0 y the maximum 1, (4) the \(\alpha\)-levels have to increase from 0 to 1, (5) the infimum values have to be non-decreasing, (6) the supremum values have to be non-creasing, (7) the infimum value has to be smaller or equal than the supremum value for each \(\alpha\)-level. This function is used internally in some of the other functions to do a preliminary checking if the input data are in the correct form.

The function checks if the input data are given in the correct form of a matrix of dimension n x 4 containing n trapezoidal fuzzy numbers characterized by their four values inf0,inf1,sup1,sup0 each. The following conditions have to be fulfilled: (1) the number of columns of the matrix must be 4 (the four values characterizing each trapezoidal fuzzy number), (2) the four values of each trapezoidal number have to be non-decreasing. This function is used internally in almost all the other functions to do a preliminary checking if the input data are in the correct form.
