In teaching numerical solutions for partial differential equations,specifically the finite difference method for Poisson's equation,a problem-oriented heuristic approach is used.Based on the concept of differences,four types of algebraic equations are constructed with grid node values as degrees of freedom.This transforms the problem into solving these algebraic equations.Combining this with program design enhances teaching quality.
