摘要：

Various normwise relative condition numbers that measure the sensitivity of Drazin inverse and the solution of singular linear systems are characterized. The sensitivity of condition number itself is then investigated. Finally, upper bounds are derived for the sensitivity of structured perturbation. (C) 2002 Elsevier Inc. All rights reserved.
