Given a sample of trapezoidal fuzzy numbers contained in a matrix F
, the function calculates the variance of these numbers with respect to the mid/spr distance. The function first checks if the input matrix F
is given in the correct form (tested by checkingTra
).
1 | Var(F, a = 1, b = 1, theta = 1/3)
|
F |
matrix of dimension |
a |
number >0, by default |
b |
number >0, by default |
theta |
number >0, by default |

The function returns the variance of the sample with respect to the mid/spr distance, which is a real number.
