Cij equals (−1)i+j times the determinant of the n − 1 by n − 1 square matrix obtained by removing row i and column j. (Cij is positive if i + j is even and negative if i + j is odd.)

In linear algebra, the adjugate or classical adjoint of a square matrix A is the transpose of its cofactor matrix and is denoted by adj(A). It is also occasionally known as adjunct matrix, or "adjoint", though the latter term today normally refers to a different concept, the adjoint operator which for a matrix is the conjugate transpose. The product of a matrix with its adjugate gives a diagonal matrix (entries not on the main diagona… WebThe Cofactor is the number you get when you remove the column and row of a designated element in a matrix, which is just a numerical grid in the form of rectangle or a square. … inch and a half deep well socketWebEigenvector Trick for 2 × 2 Matrices.
