Sep 09, 2017 · This paper investigates the problem of simultaneous approximation of a prescribed multidimensional frequency response. The frequency responses of multidimensional IIR digital filters are used as nonlinear approximating functions. Chebyshev approximation theory and the notion of line homotopy are used to reveal the approximation properties of this set of IIR functions. A sign condition is ...

interval [9]. The MPS and Chebyshev polynomials have been used for solving partial di erential equations (PDE). For example, the paper [13] solved elliptic partial di erential equation boundary value problems; the paper [11] studied two dimensional heat conduction problems and the authors used Chebyshev

polynomial in chapter 6. In chapter 6 we show Chebyshev’s solution to the approximation problem, compare this to the approximation in the L2-norm, give some other techniques to solve the problem and show some utilities. At the end of this chapter, we show some examples using the di erent tech-niques.

CHEBYSHEV POLYNOMIAL APPROXIMATION TO SOLUTIONS OF ORDINARY DIFFERENTIAL EQUATIONS By Amber Sumner Robertson May 2013 In this thesis, we develop a method for nding approximate particular so-lutions for second order ordinary di erential equations. We use Chebyshev polynomials to approximate the source function and the particular solution of

The problem of calculating the best approximating straight line--in the sense of Chebyshev--to a finite set of points in R" is considered.

such problem using orthogonal Chebyshev polynomials. It is completely different method of approximation, where the maximum difference between value of function and value calculated from polynomial is minimized. In the paper there are presented properties of Chebyshev polynomials, their

violating the necessary condition for Chebyshev approximation given by theorem 1 that equations (2) be insoluble. The same would apply if the negative sign had been chosen in (6). Thus (6) is not the desired polynomial. To solve our problem we note …

The Chebyshev approximation problem in R,, n has no closed form solution, but the same problem in /~,,, does. Here we present that solution. The theory has a clear beginning in the seminal paper of Carath6odory and Fej6r in 1911 [5], which considered the polynomial case re=n=0. This original theory was
