摘要:
This paper introduces find exemplifies discrete weighted residual methods (DWRM's) for the approximate solution of discrete boundary-value problems in ordinary and partial difference equations. The solution of the discrete boundary-value problem is approximated by a linear combination of known functions with undetermined coefficients. DWRM's specify procedures for determining these coefficients as the solution of a. system of algebraic equations
