We prove that if (u h (z)) h¿0 is a family of meromorphic functions which converges to a meromorphic function u(z), then [M; N ] u h → u when (h; M ) → (0; +∞), where [M; N ] u h denotes the least-squares multivariate PadÃ e approximants (LSPA) of u h . This property is fundamental when using the LS
