The authors describe the set of MAPLE procedures that are intended for updating pseudo-inverse matrices under their modification of the form \(A\mapsto A+cd^*\) in particular cases where one entry \(a_{ij}\) changes in the matrix \(A\), or one column of \(A\) is removed, or one additional column (or row) is added to \(A\). The procedures are illustrated by numerical experiments described in the paper.
