| Abstract: | To introduce the moving least-squares approximation and the interpolating moving least-squares method,then applied respectively two kinds of methods to surface fitting,the two algorithms use MATLAB programming,compared the exact solution with two numerical solutions,the results show that the precision of the interpolating moving least-squares method is higher. |
