Considering the definition of LR fuzzy number in `LR`

, it is obvious that * (n, α, β)RL * will be a RL fuzzy number.
Function `RL`

introduce a total form for RL fuzzy number to computer.

1 |

`m` |
The core of RL fuzzy number |

`m_l` |
The left spread of RL fuzzy number |

`m_r` |
The right spread of RL fuzzy number |

This function help to users to define any RL fuzzy number after introducing the left shape and the right shape functions L and R. This function consider RL fuzzy number RL(m, m_l, m_r) as a vector with 4 elements. The first three elements are m, m_l and m_r respectively; and the fourth element is considerd equal to 1 for distinguish RL fuzzy number from LR and L fuzzy numbers.
