Matriz de menores y cofactores

Un menor M_{i, j} es el determinante de una matriz cuadrada formado mediante la eliminación de la fila i y la columna j de una matriz cuadrada de mayor tamaño A.
Un cofactor C_{i, j} es menor M_{i, j} cuando i+j es par y −M_{i, j} cuando i+j es impar, por lo tanto C_{i, j}=(−1)^i+jM_{i, j}
