#### Abstract

$\lim\limits _{\alpha \to 0} \left( \alpha I+A^*A\right) ^{-1} A^*$ from

[\v Zukovski, Lipcer, On recurent computation of normal solutions of linear algebraic equations, \v Z. Vicisl. Mat. i Mat. Fiz. 12 (1972), 843--857] and

[\v Zukovski, Lipcer, On computation pseudoinverse matrices, \v Z. Vicisl. Mat. i Mat. Fiz. 15 (1975), 489--492]. The iterative process for the implementation of the general limit formula

$\lim\limits _{\alpha \to 0}(\alpha I+R^*S) ^{-1}R^*$

was defined in [P.S. Stanimirovi\'c, Limit representations of generalized inverses and related methods, Appl. Math. Comput. 103 (1999), 51--68].

In this paper we develop an improvement of this iterative process.

The iterative method defined in such a way is able to produce the result in a predefined number of iterative steps. Convergence properties of defined iterations are further investigated.
