WebTake P = b11T (outer product!) and observe that A = P + (a − b)I. We begin with observations on the matrix P = b11T: All rows and columns are equal and b > 0, so P is a rank 1 matrix. Thus λ1 = 0 is an eigenvalue of multiplicity n − 1. P1 = b11T1 = nb1. Thus λ2 = nb is an eigenvalue of multiplicity 1. We now use the following theorem:
