Formulation of pseudospectral meshless radial point Hermit interpolation for the Motz problem and comparison to pseudospectral meshless radial point interpolation

摘要

Purpose - The purpose of this paper is to develop pseudospectral meshless radial point Hermit interpolation (PSMRPH1) for applying to the Motz problem. Design/methodology/approach - The author aims to propose a kind of PSMRPHI method. Findings - Based on the Motz problem, the author aims also to compare PMRPHI and PSMRPI which belong to more influence type of meshless methods. Originality/value - Although the PSMRPHI method has been infrequently used in applications, the author proves it is more accurate and trustworthy than the PSMRPI method.
