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…
