In the present paper we deduce closed form expressions for the entries of the Moore–Penrose inverse of a special type upper bidiagonal matrices. On the base of the formulae obtained, a finite algorithm with optimal order of computational complexity is constructed.
Keywords: generalized inverse, Moore–Penrose inverse
Mots-clés : bidiagonal matrix.
