Introduction
- What is an Adjoint? The adjoint of a square matrix, often denoted as adj(A), is the transpose of the matrix of cofactors of A.
\[\Large \text{adj}(A) = C^T\]
- In the above formula,
- adj(A) – Adjoint of A
- CT – Transpose of the Cofactor Matrix of A
- Why is it Important? The adjoint is essential in matrix algebra, especially for finding the inverse of a matrix and solving systems of linear equations.
It is required to have understood the following topics before proceeding with the lesson
