On Chebyshev-type discrete quasi-interpolants

Ibáñez-Pérez, María José - In: Mathematics and Computers in Simulation (MATCOM) 77 (2008) 2, pp. 218-227

In this paper new discrete quasi-interpolants on the real line are defined with good error constants for enough regular functions. Some oversampling is permitted in order to have some freedom degrees and so a minimization problem is established. This problem has always a solution that can be...
