### Generalized Null Space Decomposition and Drazin Inverse

A MATLAB package to compute the Generalized Null Space Decomposition of a real or complex matrix
(aka the Staircase Form), identifying the Jordan block structure for the zero eigenvalues of
the matrix,
along with its Drazin inverse.

The method is documented in
this paper.
The Drazin inverse is discussed in Appendix A.
