i solved equation numerical with finite diferencial method..
and also needed analytical sollution for comparison..
finaly few minutes ago i found my error..

it wasn't placed in calculation like i was thinkig,
but in my Matlab program which i used for drawing sollution...
Hi,
My 2D L.e.:
Uxx + Uyy = 0
with boundary conditions:
U (x,0) =x
U (0,y) =0
U (1,y) =1
U (x,1) =x
Please, need help with analytical sollution!
i'm trying to do smth like it is described in attachment pic, but i it's not working..
Thanks!
