I want to use POISOLV to solve a poisson's equation. But I got some trouble in
how to specify mesh P,E,T
I appreciate it very much if anybody can help me
the question i am doing is :
on unit square [0,1]X[0,1], I have Dirichlet boundary condition and discrete
laplacian at every point in side. Then I want to apply POISOLV to solve it....
Thanks a lot!

Why not using "pdetool", the mesh is done automatically.

Then how specify regular grid?
and how to give the boundary condition, which i will update every
iteration....

trouble in
discrete
it....
