On polynomial and barycentric interpolations
The present survey collects some recent results on barycentric interpolation showing the similarity to the corresponding Lagrange (or polynomial) theorems. Namely we state that the order of the Lebesgue constant for barycentric interpolation is at least log n; we state a Grünwald–Marcinkiewicz type theorem for the barycentric case; moreover we define a Bernstein type process for the barycentric...
متن کاملSets, Partitions and Functions Interpolations
This paper presents the use of the SKIZ transformation to interpolate sets, partitions and functions. This transformation generates a sequence of intermediary sets which can be used to de ne a distance between the interpolated sets. Other distances are also introduced. These distances could be useful to generalise the interpolation algorithm. Some examples of use are given.
متن کاملAre interpolations in metallicity reliable ?
In this proceeding we present the procedure that we have adopted to obtain a dataset of Padova94 tracks (Bressan et al.(1993), Fagotto et al.(1994), Fagotto et al.(1994)) interpolated in metallicity. The procedure requires special care to avoid spurious features in the resulting grid, thus we have subdivided tracks in evolutionary phases, we have chosen the suitable interpolation method and the...
متن کاملInterpolations with Elasticae in Euclidean Spaces
Motivated by interpolation problems arising in image analysis, computer vision, shape reconstruction and signal processing, we develop an algorithm to simulate curve straightening flows under which curves in R of fixed length and prescribed boundary conditions to first order evolve to elasticae, i.e., to (stable) critical points of the elastic energy E given by the integral of the square of the...
متن کاملTime - Frequency Signal Representations Using Interpolations in
Time-Frequency Signal Representations Using Interpolations in Joint-Variable Domains Report Title Time-frequency (TF) representations are a powerful tool for analyzing Doppler and micro-Doppler signals. These signals are frequently encountered in various radar applications. Data interpolators play a unique role in TF signal representations under missing samples. When applied in the instantaneou...
