Additionally, advancements in parallel computing frameworks have invigorated classical matrix iteration methods, providing robust solutions for large, sparse generalised eigenvalue problems.

In this paper some of the numerical problems associated with computing the generalized inverse of a matrix are discussed and illustrated by a detailed analysis of an iteration of Ben-Israel and Cohen.
