adjoint of a matrix

Let us learn about adjoint of a matrix & its properties

1. A.(adj A) = (adj A). A = |A| I

2. adj (AB) = (adj B) . (adj A).

Non-singular Matrix & Singular Matrix

A square matrix A is called non-singular if its determinant value is non-zero.

That is a square matrix A = [aij]nxn is called non – singular if lAl # 0.

A square matrix A is called singular if |A| = 0.
