A method is given that will numerically find the closest normal matrix N (in the Frobenius norm) to a given matrix A by a sequence of unitary similarities. In the coordinate system of the eigenvectors of N, the obesity matrix of A is Hermitian. There is also a chapter with computed examples for the numerical ranges of N and A.
