Given a sample of trapezoidal fuzzy numbers contained in a matrix `F`

, the function calculates the *\varphi*-wabl/ldev/rdev median of these numbers, characterized by means of `nl`

equidistant *α*-levels (by default `nl`

=101), including always the 0 and 1 levels, with their infimum and supremum values. The function first checks if the input matrix `F`

is given in the correct form (tested by `checkingTra`

).

1 | ```
Medianwabl(F, nl = 101, a = 1, b = 1)
``` |

`F` |
matrix of dimension |

`nl` |
positive integer, by default |

`a` |
number >0, by default |

`b` |
number >0, by default |

See examples

The function returns the *\varphi*-wabl/ldev/rdev median, given by an array of dimension `nl x 3 x 1`

where `nl`

is the number of considered *α*-levels and 3 the number of columns of the array: the first column will be the *α*-levels, the second one their infimum values and the third one their supremum values.
