@Deprecated
public interface Schur<N extends Number>
extends MatrixDecomposition<N>

Schur: [A] = [Q][U][Q]^-1 [A] = [Q][U][Q]^-1 where:

• [A] is a square complex entry matrix.
• [Q] is a unitary matrix (so that [Q]^-1 equals [Q]^H).
• [U] is an upper triangular matrix, which is called a Schur form of [A]. Since [U] is similar to [A], it has the same multiset of eigenvalues, and since it is triangular, those eigenvalues are the diagonal entries of [U].
