A Note on P -Regular Splitting of Hermitian Matrix
Zhi‐Hao Cao · SIAM Journal on Matrix Analysis and Applications · 2000
In this note we examine the spectral property of the iteration matrix induced by the P-regular splitting of an invertible Hermitian matrix and point out that a theorem given by Weissler (cf. Theorem A2 in [ SIAM J. Matrix Anal. Appl., 16 (1995), pp. 448--461]) is incorrect.
