摘要：

We present a unified representation theorem for Drazin inverse. Specific expression and computational procedures for Drazin inverse can be uniformly derived. Numerical examples are tested and the application to the singular linear equations is also considered. (C) 2000 Elsevier Science B.V. All rights reserved. MSG: 15A09; 65F20.
