A new multiquadric quasi‐interpolation operator with interpolation property

Mathematical Methods in the Applied Sciences, 2013
In this article, we discuss a class of multiquadric quasi‐interpolation operator that is primarily on the basis of Wu–Schaback's quasi‐interpolation operator and radial basis function interpolation. The proposed operator possesses the advantages of linear polynomial reproducing property, interpolation property, and high accuracy.

Multiquadric trigonometric spline quasi-interpolation for numerical differentiation of noisy data: a stochastic perspective

Numerical Algorithms, 2017
The multiquadric trigonometric kernel was defined by \textit{W. Gao} and \textit{Z. Wu} [J. Comput. Appl. Math. 271, 20--30 (2014; Zbl 1326.65021)] as \(\phi(x)=\sqrt{c^2 + \sin^2 (x/2)}\), where \(c\) is a nonnegative shape parameter. The paper under review proposes a quasi-interpolation method for numerical differentiation of noisy data, based on the

Solving one dimensional nonlinear coupled Burger's equations using high accuracy multiquadric quasi-interpolation

2020
Summary: In this paper a multiquadric quasi-interpolation (MQQI) scheme for solving the system of 1-D coupled nonlinear Burger's equations (CNBE) is presented. The scheme utilizes the derivative of the quasi-interpolation for approximating the spatial derivative and the Taylor series expansion for temporal derivatives.
