Question

Every square matrix is similar to a diagonal matrix. pls jutify ​

Answer 1

Step-by-step explanation:

Over the field of real or complex numbers, more is true. The spectral theorem says that every normal matrix is unitarily similar to a diagonal matrix (if AA∗ = A∗A then there exists a unitary matrix U such that UAU∗ is diagonal)
