This function calculates the (\varphi,θ)-wabl/ldev/rdev distance between the trapezoidal fuzzy numbers contained in two matrixes, which should be given in the desired format. For this, the function first checks if the input matrixes R
and S
are in the correct form (tested by checkingTra
).

The function returns a matrix of dimension r x s
containing the (\varphi,θ)-wabl/ldev/rdev distances between the trapezoidal fuzzy numbers of the matrix R
and the trapezoidal fuzzy numbers of the matrix S
.
