On two families of near-best spline quasi-interpolants on non-uniform partitions of the real line
Domingo Barrera, Maria José Ibañez Pérez, Paul Sablonnière +1
The univariate spline quasi-interpolants (abbr. QIs) studied in this paper are approximation operators using B-spline expansions with coefficients which are linear combinations of…

Near-best univariate spline discrete quasi-interpolants on non-uniform partitions
D. Barrera, M. J. Ibanez, Paul Sablonniere +1
Univariate spline discrete quasi-interpolants (abbr. dQIs) are approximation operators using B-spline expansions with coefficients which are linear combinations of discrete values…
