چکیده
|
We consider the perturbation analysis of the matrix equation x - σi = 1 m a* i x a i + σj = 1 n bj * xbj = i. based on the matrix differentiation,we first give a precise perturbation bound for the positive definite solution. a numerical example is presented to illustrate the sharpness of the perturbation bound. © 2012 xue-feng duan and qing-wen wang.
