PROGRAM FOR SOLVING THE BOUNDARY PROBLEM FOR THE SYSTEM OF DIFFERENTIAL EQUATIONS In this work the description of the computational scheme and procedure realizing the sweep method for solving the system of two ordinary differential equations with 2th type boundary conditions at the ends points of given interval is represented. The boundary problem is approximated with the help of the difference scheme of O(h^4) precision on the mesh with constant step h. This problem occurs in schemes of linearity of nonlinear boundary problems (for example, in newtonian iterative schemes), and represented here approach gives the possibility to receive the precision of approximation with power O(h^4). Sources and the detailed description (in Russian) are submitted. |
