Development of the Improved Method of Grids

Abstract

The purpose of this paper is to develop and generalize the improved method of grids (method of finite differences) described in (Kollats, 1969) to calculation a partial derivative. The method of uncertain coefficients is applied to the two dimensional boundary value problems. For obtaining of interpolation polynomials, the matrixes are used. The essential simplification of the calculation formulae is received. The numerical results are presented.
