Hi,
I'd like to solve the PDE
$\partial u / \partial t = r*(\partial/\partial r[r*D0*(u/u0)^n])$
where D0, C0 and n are constants and $u=u(r,t)$
using the PDE toolbox. However, I don't seem to be able to find a way to set it up - mainly finding the coefficients to specify the PDE. Is there a way to do it? Any help would be much appreciated.
Thanks!

Generally, PDE Toolbox solves problems with second-order spatial derivatives. If you can manage to convert your problem into this form, then you can specify coefficients as documented.
Good luck,
