A rational quasi-interpolation operator for functions with jumps without the Gibbs phenomenon
Francesco Dell'Accio, Francesco Larosa, Federico Nudo +1
The study of quasi-interpolation has gained significant importance in numerical analysis and approximation theory due to its versatile applications in scientific and engineering fi…
rational approximation and quasi-histopolation of functions with jumps through multinode Shepard functions
Francesco Dell'Accio, Francesco Larosa, Federico Nudo +1
Histopolation, or interpolation on segments, is a mathematical technique used to approximate a function over a given interval by exploiting integral information over…
Numerical cubature on scattered data by adaptive interpolation
R. Cavoretto, F. Dell'Accio, A. De Rossi +4
We construct cubature methods on scattered data via resampling on the support of known algebraic cubature formulas, by different kinds of adaptive interpolation (polynomial, RBF, P…
Numerical differentiation on scattered data through multivariate polynomial interpolation
Francesco Dell'Accio, F. Di Tommaso, N. Siar +1
We discuss a pointwise numerical differentiation formula on multivariate scattered data, based on the coefficients of local polynomial interpolation at Discrete Leja Points, writte…
