TransfTra:

Description

This function transforms a matrix of dimension n x 4 containing n trapezoidal fuzzy numbers characterized by their four values inf0,inf1,sup1,sup0 into an array of dimension nl x 3 x n containing these n fuzzy numbers characterized by means of nl equidistant \(\alpha\)-levels each (by default nl=101). The function first checks if the input matrix F is given in the correct form (tested by checkingTra). In case yes, the function returns an array given in the format explained in the function checking.

Usage

TransfTra(F, nl = 101)

Arguments

matrix of dimension n x 4 containing n trapezoidal fuzzy numbers characterized by their four values inf0,inf1,sup1,sup0. The function implicitly checks if the matrix is in the correct form (tested by checkingTra).

positive integer, by default nl=101. It indicates the number of desired \(\alpha\)-levels for characterizing the trapezoidal fuzzy numbers.

Value

The function returns an array of dimension nl x 3 x n containing the n trapezoidal fuzzy numbers characterized by means of nl \(\alpha\)-levels. The first column of the array are the \(\alpha\)-levels, the second one their infimum values and the third one their supremum values. The correct format of the array is explained in the function checking.
