A11=(-1)^2 *(b22 * c33 - b23 *c32)= b22*c33-b23*c32
A12=(-1)^3 *(b21 * c33- b23 * c31)=-b21*c33+b23*c31
A13=(-1)~4 *(b21 * c32- b22* c31)=b21 *c32- b22*c31
B21=(-1)~3 * (a12 * c33- a13 * c32)=-a12* c33 + a13*c32
……
C33= (-1)^6 * (a11 * b22 - a12 * b21)=a11 * b22 - a12*b21
然后伴随矩阵就是
A11 A12 A13
B21 B22 B23
C31 C32 C33
的转置 矩阵AT(T为上标)
