摘要
The Kantorovich-Wielandt angle theta(A) and the author's operator angle phi(A) are related by cos phi(A(2)) = sin theta(A). Here A is an arbitrary symmetric positive definite (SPD) matrix. The relationship of these two different geometrical perspectives is discussed. An extension to arbitrary nonsingular matrices A is given. A related four-way relationship with the operator trigonometry, strengthened CBS constants, and domain decomposition methods is noted. (C) 1999 Elsevier Science Inc. All rights reserved.
