• elementele aflate pe diagonala principală a matricei vor primi valoarea 0
• elementele de pe prima coloană, cu excepţia celui aflat pe diagonala principală vor primi valoarea n
• elementele de pe a doua coloană, cu excepţia celui aflat pe diagonala principală vor primi valoarea n-1
  …
• elementele de pe ultima coloană, cu excepţia celui aflat pe diagonala principală vor primi valoarea 1
