High order interpolation
WebJun 3, 2015 · High-order interpolation algorithms for charge conservation in Particle-in-Cell (PIC) simulations are presented. The methods are valid for the case that a particle trajectory is a zigzag line. The second-order and third-order algorithms which can be applied to any even-order and odd-order are discussed in this paper, respectively. Several test ...

Abstract: The interpolation errors are analyzed by applying the high order interpolation … WebJun 11, 2008 · A linear, or first degree polynomial (many use the words "order" and "degree" interchangeably), might be written mathematically as y (x) = a1*x + a2. In MATLAB we will merely store the coefficients, as a vector [a1,a0]. Note that a polynomial in MATLAB has it's coefficients stored with the highest order term first. P1 = polyfit (x,y,1)
WebThe 4x-interpolation filter is implemented as a cascade of two 2x-interpolation filters, each of which can be configured for either low-pass or high-pass response. This enables the user to select one of the higher order images present at multiples of the input data rate clock while maintaining a low date input rate.

WebAug 20, 2015 · However, it seems the existing Cubic-Polynomial Interpolation scheme are restricted to uniform rectangular meshes. Consequently, this scheme has some limitations to problems in irregular domains. This paper will extend the Cubic-Polynomial Interpolation scheme to triangular meshes by using some spline interpolation techniques.
