Polynomial fitting and interpolation on circular sections
نویسندگان
چکیده
We construct Weakly Admissible polynomial Meshes (WAMs) on circular sections, such as symmetric and asymmetric circular sectors, circular segments, zones, lenses and lunes. The construction resorts to recent results on subperiodic trigonometric interpolation. The paper is accompanied by a software package to perform polynomial fitting and interpolation at discrete extremal sets on such regions. 2000 AMS subject classification: 41A10, 41A63, 65D05.

gH-differentiable of the 2th-order functions interpolating
Fuzzy Hermite interpolation of 5th degree generalizes Lagrange interpolation by fitting a polynomial to a function f that not only interpolates f at each knot but also interpolates two number of consecutive Generalized Hukuhara derivatives of f at each knot. The provided solution for the 5th degree fuzzy Hermite interpolation problem in this paper is based on cardinal basis functions linear com...

In this paper, combining with the examples, we focus on the study of general Kinematics modeling and simulation of Four degrees of freedom carrying manipulator based on laboratory development. On the basis of calculating kinematic positive and inverse solutions, a space trajectory curve is planed which is composed of three sections of straight lines and two pieces of circular arc. For 4R manipu...
متن کاملPolynomial Meshes: Computation and Approximation
We present the software package WAM, written in Matlab, that generates Weakly Admissible Meshes and Discrete Extremal Sets of Fekete and Leja type, for 2d and 3d polynomial least squares and interpolation on compact sets with various geometries. Possible applications range from data fitting to high-order methods for PDEs.
متن کاملComplex Hermite Polynomials: from the Semi-circular Law to the Circular Law
We study asymptotics of orthogonal polynomial measures of the form |HN |2dγ where HN are real or complex Hermite polynomials with respect to the Gaussian measure γ. By means of differential equations on Laplace transforms, interpolation between the (real) arcsine law and the (complex) uniform distribution on the circle is emphasized. Suitable averages by an independent uniform law give rise to ...
متن کاملCurve Fitting And Interpolation Model Applied In Nonel Dosage Detection
The Curve Fitting and Interpolation Model are applied in Nonel dosage detection in this paper firstly, and the gray of continuous explosive in the Nonel has been forecasted. Although the traditional infrared equipment establishes the relationship of explosive dosage and light intensity, but the forecast accuracy is very low. Therefore, gray prediction models based on curve fitting and interpola...
