FuzzyNumbersToMatrix: Conversion of a list of fuzzy numbers into a matrix.

Description

`FuzzyNumbersToMatrix` converts a list of triangular or trapezoidal fuzzy numbers into a matrix.

Usage

FuzzyNumbersToMatrix(fuzzyList, trapezoidal = TRUE, varNames = NA, ...)

Value

The output is given as a matrix with 3 (for triangular fuzzy numbers) or 4 (for trapezoidal ones) columns and the number of rows is equal to number of fuzzy values.

Arguments

fuzzyList

Name of the list with fuzzy numbers.

trapezoidal

Logical value depending on the type of fuzzy values (triangular or trapezoidal ones).

varNames

Optional names for columns of the output matrix.

...

Additional parameters passed to other functions.

Details

The procedure converts the given list of triangular or trapezoidal fuzzy numbers into a matrix. It is necessary to select the appropriate type of these fuzzy numbers (using trapezoidal=FALSE for triangular fuzzy numbers or the default trapezoidal=TRUE for trapezoidal ones) The output matrix has 3 (for triangular fuzzy numbers) or 4 (for trapezoidal ones) columns with the values of the left supports, cores (or the left and right ends of the cores for trapezoidal fuzzy cores) and right supports. Each row is related to single fuzzy number.

Examples

# seed PRNG

set.seed(1234)

# load the necessary library

library(FuzzySimRes)

# generate sample of trapezoidal fuzzy numbers with FuzzySimRes library

list1<-SimulateSample(20,originalPD="rnorm",parOriginalPD=list(mean=0,sd=1),
incrCorePD="rexp", parIncrCorePD=list(rate=2),
suppLeftPD="runif",parSuppLeftPD=list(min=0,max=0.6),
suppRightPD="runif", parSuppRightPD=list(min=0,max=0.6),
type="trapezoidal")

# check the first fuzzy number

list1$value[[1]]

# convert fuzzy numbers to a matrix and check the first value

head(FuzzyNumbersToMatrix(list1$value))
