Elementarne transformacije nam daju drugipostupak za racunanje inverzne matrice: Neka je A matrica reda n. Formiramo matricu tipan 2n oblika[A j I]gdje je I jedinicna matrica (istog reda kao ipolazna). Elementarnim transformacijama nad retcimamatricu [A j I] svodimo na oblik [I j B] :[A j I] [I j B]Ako je to moguće, A je regularna i A 1 = B:Ako to nije moguće, tada je A singularna matrica.
