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 nlα-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 α-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 α-levels, (3) the minimum α-level should be 0 y the maximum 1, (4) the α-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 α-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.
checking(R)
Arguments
R: can be any array.

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