Solving non-linear PDE

Hello everybody,

I am trying to solve a PDE which has the form:

dC/dt = (5+c)^2/{(5+c)^2+5}d2C/dx2

Can Matlab solve such a equation like that? If it can, how can I set it up?

I would appreciate for any help.

Thank you for your help in advance.

MATLAB can very much solve..anything......have a look on ode45.....if you want to solve it numerically.....have a look on dsolve if you want to solve it analytically..

Rewrite the equation as

[(5+c)^2/{(5+c)^2+5}]^(-1) * dC/dt = d^2C/dx^2

and use MATLAB's "pdepe".

Best wishes
