checkingTra {FuzzyStatTra} | R Documentation |
Checking correct data format (as matrix)
Description
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.
Usage
checkingTra(F)
Arguments
F |
can be any matrix. |

Value
The function returns the value 1 if the input fulfills all conditions, if not, the value 0 is returned.
