On Orthogonal Polynomials with Regularly Distributed Zeros

In this case the points 0k,, = are sin xkn are equidistributed in Weyl's sense . A non-negative measure da for which the array xkn (da) has the distribution function fl o(t) will be called an arc-sine measure . If du(x) = w(x) dx is absolutely continuous, we apply, replacing dca by w, the notations pn(W,x), yn (w), xkn(w) and call a non-negative w(x) an arc-sine weight if da(x) = w(x) dx is an ...

SCANMACS | Scan Macros for Regularly Distributed Arrays

SCANMACS is a portable set of C macros for instantiating families of high performance scan (parallel preex) functions for use on regularly distributed arrays. An implementation of the scan intrinsics in the HPF standard library is described, including modiications to the compiler.

Homogeneous Interpolation on Ten Points

In this paper we prove that for all pairs (d,m) with d/m ≥ 174/55, the linear system of plane curves of degree d with ten general base points of multiplicity m has the expected dimension.

Rational Interpolation at Chebyshev points

The Lanczos method and its variants can be used to solve eeciently the rational interpolation problem. In this paper we present a suitable fast modiication of a general look-ahed version of the Lanczos process in order to deal with polynomials expressed in the Chebyshev orthogonal basis. The proposed approach is particularly suited for rational interpolation at Chebyshev points, that is, at the...

Newton Interpolation in Fejér and Chebyshev Points

Let T be a Jordan curve in the complex plane, and let Í) be the compact set bounded by T. Let / denote a function analytic on O. We consider the approximation of / on fî by a polynomial p of degree less than n that interpolates / in n points on T. A convenient way to compute such a polynomial is provided by the Newton interpolation formula. This formula allows the addition of one interpolation ...
