摘要: We define a new average — termed the resolvent for positive semidefinite matrices. For definite matrices, enjoys self-duality and it interpolates between harmonic arithmetic averages, which approaches when taking appropriate limits. compare to geometric mean. Some applications matrix functions are also given.
