Množenje matrice u C: Možemo zbrajati, oduzimati, množiti i dijeliti 2 matrice. Da bismo to učinili, od korisnika unosimo podatke o broju retka, broju stupca, prvim elementima matrice i drugim elementima matrice. Zatim vršimo množenje na matricama koje je unio korisnik.
niz u c++
U množenju matrica prva matrica jedan element retka se množi sa drugom matricom svi elementi stupca .
Pokušajmo razumjeti množenje matrice 2*2 i 3*3 matrice prema donjoj slici:

Pogledajmo program množenja matrica u C-u.
