Aljebra linealean, matrize karratu bateko a i , j {\displaystyle a_{i,j}\,\!} elementu bati dagokion adjuntua A i , j {\displaystyle A_{i,j}\,\!} zenbaki bat da, non A i , j = ( − 1 ) i + j ⋅ M i , j {\displaystyle A_{i,j}=(-1)^{i+j}\cdot \ M_{i,j}\,\!} den, M i , j {\displaystyle M_{i,j}\,\!} a i , j {\displaystyle a_{i,j}\,\!} elementuari dagokion minorra izanik.
A = ( 1 2 3 4 5 6 7 8 9 ) {\displaystyle A={\begin{pmatrix}1&2&3\\4&5&6\\7&8&9\end{pmatrix}}}
