# Find an invertable matrix P such that $P^{-1}$ is diagonal.

Find an invertable matrix P such that $P^{-1}$$AP$ is diagonal. Hint: use eigendecomposition.

$\begin{matrix} 4 & 0 & 0 \\ 3 & 2 & 0 \\ 0 & 2 & 1 \end{matrix}$

• Are you sure the question statement is correct ? Is it P inverse or D as per diagonalization

• If the given matrix is A then you need to find A= PD(P^-1) where P is invertible and D is diagonal?

• Sorry, missed it in the formula creator

• Okay so basically we need to do a decomposition
