An automatic methodology for obtaining optimum shape factors for the radial point interpolation method

open access: yesJournal of Microwaves, Optoelectronics and Electromagnetic Applications
In this letter, a methodology is proposed for automatically (and locally) obtaining the shape factor c for the Gaussian basis functions, for each support domain, in order to increase numerical precision and mainly to avoid matrix inversion ...
