Adjugate Matrix

$\adj {\mathbf A}$

Let $\mathbf A = \sqbrk a_n$ be a square matrix of order $n$.

Let $\mathbf C$ be its cofactor matrix.

The adjugate matrix of $\mathbf A$ is the transpose of $\mathbf C$:

$\adj {\mathbf A} = \mathbf C^\intercal$

The $\LaTeX$ code for \(\adj {\mathbf A}\) is \adj {\mathbf A} .
