Optimal Shape Factor and Fictitious Radius in the MQ-RBF:Solving Ill-Posed Laplacian Problems
《Computer Modeling in Engineering & Sciences》2024年第6期3189-3208,共20页Chein-Shan Liu Chung-Lun Kuo Chih-Wen Chang 
supported by the the National Science and Technology Council(Grant Number:NSTC 112-2221-E239-022).
To solve the Laplacian problems,we adopt a meshless method with the multiquadric radial basis function(MQRBF)as a basis whose center is distributed inside a circle with a fictitious radius.A maximal projection techniq...
