摘要: Lagrange interpolation is extended to the complex plane in this paper. It turns out be composed of two parts: polynomial and rational interpolations an analytical function. Based on plane, a variable boundary collocation approach constructed. The method truly meshless singularity free. features high accuracy obtained by use small number nodes as well dimensionality advantage, that is, two-dimensional problem reduced one-dimensional one. applied problems theory elasticity. Numerical examples are very good agreement with ones. easy implemented capable able give stress states at any point within solution domain.
