【Abstract】 In this paper,some improvements for the trial function of two and three dimentional problems, a sparse algorithm based on the subregions for solving the equation system of residual value and a basic frame of general purpose program of weighted residual method are given. The results of numerical examples show that its precision by using less located points is excellent.更多还原
