 Matrix.Tridiagonalize(M) returns the matrix in triple-diagonal form. The first element returned is a try-diagonal response function representing the matrix. The second element returned is a matrix that represents the unitary matrix that transforms the Hermitian matrix M to try-diagonal form. Possible options include Matrix.Tridiagonalize(M) returns the matrix in triple-diagonal form. The first element returned is a try-diagonal response function representing the matrix.
