MoazamiDepartment of Mathematics, Faculty of Mathematical Sciences and Statistics, Malayer University, Malayer, Iran.Journal Article19700101The main purpose of this article is to describe a numerical scheme for solving three-dimensional linear Fredholm integral equations of the second kind on the cubic domains. The method is based on interpolation by radial basis functions (RBFs) based on Gauss-Legendre nodes and weights. Error analysis is presented for this method. Finally, several examples are given and numerical examples are presented to demonstrate the validity and applicability of the method.https://ijnao.um.ac.ir/article_24549_9bffd7ba440c0dd9c09c1905b05bf307.pdf
