The problem of the numerical calculation of the Moore–Penrose pseudoinverse is considered. Two of the most frequently used computational techniques are analyzed by means of the introduction of the concept: ϵ- – numerical pseudoinverse. A new algorithm using RRQR factorization is proposed, which overcomes some disadvantages of the above mentioned methods. Illustrative numerical experiments are reported.
