- Adjoint of matrix A is written by .
- The adjugate of A is the transpose of the cofactor matrix C of A, .
- Also adjoint of a matrix is defined by .
- The adjugate of 1x1 matrix is .
- The adjugate of 2x2 matrix is .
- Consider3x3 matrix

Its adjugate is the transpose of its cofactor matrix:adj(A)=C^T
