ADJOINT OF A MATRIX

Let A = [a;j ] be a square matrix of order n and C = [ be its cofactor matrix. Then, matrix CT = [Cji], is called the adjoint of matrix A and is written as

adj (A)=C7 = [C;],153j5n. T .

1 2 3] e.g. If A = -1 0 1 , then C11 = – 3, C12 = 6, C13 = - 3, -

C21 =5, C22 = -10, C23 = 5 C31 = 2, C32 = – 4 and C33 = 2 -3 6 -3 -

:: C= 5 -10
