摘要：

We propose a finite algorithm for computing Drazin inverse of two-variable polynomial matrices based on Greville's finite algorithm for computing Drazin inverse of a constant matrix. Also a three-dimensional recursive algorithm to do that is deduced. Examples show that these methods are feasible and the implementation is developed in the symbolic package MATLAB.
