I've been using Savitzky-Golay (SG) filters for quite a while, but always on 1D data, using an implementation based on the algorithm from the Numerical Recipes to calculate the kernel (mask ...

Chaotic maps have wide application areas due to their unpredictable behavior and sensitivity to initial conditions and control parameters. This paper presents a new chaotic map derived from polynomial ...

The stationary 1D Schr?dinger equation with a polynomial potentialV(q) of degreeNis reduced to a system of (complex) ... Spectral Functions, Special Functions and Selberg Zeta Function. A. Voros .

NEWTON_INTERP_1D, a C++ library which finds a polynomial interpolant to data using Newton divided differences. NEWTON_INTERP_1D needs access to the R8LIB libraries. The test code also needs access to ...

RBF_INTERP_1D is a C++ library which defines and evaluates radial basis function (RBF) interpolants to 1D data. A radial basis interpolant is a useful, but expensive, technique for definining a smooth ...

Chromatic Symmetric Function: A symmetric function that sums over proper colourings of a graph, generalising the chromatic polynomial and encapsulating graph invariants.
