Hi,

I searched through this forum and matlab documentation but somehow
didn't find the exact solution to my problem. I will appriciate any
help.

I have a system of equations:

1) a*Ux + b*Uy= c
2) Uxx + Uyy = 0 (laplace)

(with neumann boundary conditions)
which i would like to solve using the pde matlab toolbox.

what are the coefficients i need to specify to the pde gui to solve
this, or which functions to use (with what parameters)?

Thank you for your help.

Can I use for the first equation as parabolic type, where instead the
time I use y?
