Abstract: The MHD equations are complicated non-linear systems.This paper obtained equations which are linear in the complex space from MHD.The procedure of solving the equations needs the matching of the "external" solution and the "internal" solution.Central difference with the second R-K and central difference with the fourth order R-K not only improve the speed of analysis,but also assure the algorithm’s precision.The results are effective and robust.The paper analyzed the effects of the parameters Gand KI on the eigen-functionh of differential equations.

Key words: eigen-function, boundary-layer, MHD, eigen-function, boundary-layer
