Hello!

I am new to Mathematica and want to know if my problem can be solved using it.

I have a modified diffusion equation:
dc/dt == D d^2c/dx^2 - rc exp(-n t)

D: diffusion coefficient
r: reaction rate
c: concentration
n: time constant

What i need to do is finding the right parameter combination (D, r, n) in 
such a manner that the solution of the PDE corresponds to my experimental 
results. I already achieved numerical solving of the differential equation 
but i don't know if it is possible to use some fitting routine for the 
parameter optimization.

I hope i described my problem clearly.

Thanks for your help!

Alex
