===Complement===The complement, "Bijk...,pqr...", of a minor, "Mijk...,pqr...", of a square matrix, A, is formed by the determinant of the matrix A from which all the rows ("ijk...") and columns ("pqr...") associated with "Mijk...,pqr..." have been removed.
Poddeterminanta (tudi minor) (oznaka formula_1) matrike formula_2 je determinanta, ki pripada kvadratni matriki, ki jo dobimo iz matrike formula_2 tako, da v tej matriki izbrišemo eno vrstico in en stolpec.
