Multigrid Solver for scalar elliptic linear PDEs The PDE specifications need to have the format used by the PDE toolbox. The geometry description 'g' and the boundary condition description 'b' can either be the name of a function file (see the Matlab help to pdegeom and pdebound for g and b, respectively) or matrices (see decsg and assemb, respectively).

用matlab编写的多重网格程序，能有效的求出偏微分方程的精确数值解；里面即有界面又有函数接口；很好用。
