The second and fourth orders of the accuracy difference schemes are presented. A procedure of modified Gauss elimination method is used for solving these difference schemes for the two-dimensional elliptic differential equation. The method is illustrated by numerical examples.eninfo:eu-repo/semantics/openAccessElliptic equationdifference schemestabilityArticle2851027104710.2298/FIL1405027AQ2WOS:0003447754000122-s2.0-84908227612Q3
