Barycentric Hermite Interpolation

Burhan Sadiq, Divakar Viswanath

Let $z_{1}, \dots, z_{K}$ be distinct grid points. If $f_{k, 0}$ is the prescribed value of a function at the grid point $z_{k}$ , and $f_{k, r}$ the prescribed value of the $r$ \foreig…

Finite Difference Weights, Spectral Differentiation, and Superconvergence

Burhan Sadiq, Divakar Viswanath

Let $z_{1}, z_{2}, ..., z_{N}$ be a sequence of distinct grid points. A finite difference formula approximates the $m$ -th derivative $f^{(m)} (0)$ as $\sum w_{k} f (z_{k})$ , with $w_{k}$ …

Metric Entropy and the Optimal Prediction of Chaotic Signals

Divakar Viswanath, Xuan Liang, Kirill Serkh

Suppose we are given a time series or a signal $x (t)$ for $0 \leq t \leq T$ . We consider the problem of predicting the signal in the interval $T < t \leq T + t_{f}$ from a knowledge of it…
