SIAM Journal on Numerical Analysis , Abstract | PDF ( KB) () A Fourier pseudospectral method for the “good” Boussinesq equation with second-order temporal by: nonuniform-grid Chebyshev polynomial methods, which belong to a class of spectral numerical methods. Then the resulting matrices are less sparse, but what is appar-ently lost in storage requirements, is regained in speed. We do in fact keep the storage needs moderate, as we can achieve very good accuracy with a moderate number of grid by:

A new collocation method for the numerical solution of partial differential equations is presented. This method uses the Chebyshev collocation points, but, because of the way the boundary conditions are implemented, it has all the advantages of the Legendre by: Pafnuty Chebyshev's parents were Agrafena Ivanova Pozniakova and Lev Pavlovich y was born in Okatovo, a small town in western Russia, south-west of Moscow. At the time of his birth his father had retired from the army, but earlier in his military career Lev Pavlovich had fought as an officer against Napoleon's invading armies.

A treatment of the general Chebyshev approximation method as it interests physicists and engineers is given, with a detailed discussion of the properties of Chebvshev poly-nomials. Brief applications to electric circuit theory are presented.*** Introduction. Of the various means of approximating a given function, the Cheby-File Size: 1MB. compute, and that, contrary to widespread misconceptions, numerical methods based on high-order polynomials can be extremely eﬃcient and robust. This is a book about approximation, not Chebfun, and for the most part we.

They are widely used in many areas of numerical analysis: uniform approximation, least-squares approximation, numerical solution of ordinary and partial differential equations (the so-called spectral or pseudospectral methods), and so Size: KB.

Chebyshev polynomials crop up in virtually every area of numerical analysis, and they hold particular importance in recent advances in subjects such as orthogonal polynomials, polynomial approximation, numerical integration, and spectral methods.

Yet no book dedicated to Chebyshev polynomials has been published sinceand even that work focused primarily on the theoretical 5/5(3). The Chebyshev pseudospectral method for optimal control problems is based on Chebyshev polynomials of the first is part of the larger theory of pseudospectral optimal control, a term coined by Ross.

Unlike the Legendre pseudospectral method, the Chebyshev pseudospectral (PS) method does not immediately offer high-accuracy quadrature solutions. Chebyshev polynomials crop up in virtually every area of numerical analysis, and they hold particular importance in recent advances in subjects such as orthogonal polynomials, polynomial approximation, numerical integration, and spectral methods.

This textbook offers an accessible introduction to the theory and numerics of approximation methods, combining classical topics of approximation with recent advances in mathematical signal processing, highlighting the important role the development of numerical algorithms plays in data : Springer International Publishing.The Chebyshev polynomials are two sequences of polynomials, denoted T n (x) and U n (x).They are defined as follows.

By the double angle formula, = − is a polynomial in cos(θ), so define T 2 (x) = 2x 2 − other T n (x) are defined similarly, using cos(nθ) = T n (cos(θ)).Similarly, define the other sequence by sin(nθ) = U n−1 (cos(θ)) sin(θ), where we have used de.two dimensional heat conduction problems and the authors used Chebyshev polynomials and the trigonometric basis functions to approximate their equa-tions for each time step.

In their two-stage approximation scheme, the use of Chebyshev polynomials in stage one is because of the high accuracy (spectral convergence) of Chebyshev interpolation.
