Dear All,
Does anyone have any idea how to solve the following problem in Matlab:
D*C''(z) - k*C(z) = 0, subject to: C(z=0) = C_0 C'(z=L) = 0
Where C''(z) is the 2nd derivative with respect to z. Any help greatly appreciated.
Thanks,
James Champion

You would be wise to solve this by hand because it doesn't have a nontrivial solution for most values of D and k. Fortunately, it is a very well known equation that you'll find near the beginning of any book on differential equations.
