A simulation by hand with X too large

Let us run one or two time steps for a very simple linear simulation we assume that we start with all Cj = l(i = l,. .. n), that Cq = 0 always, and X = 1. The digitised diffusion equation (point method) is then, Eq. 3.26, 

There are no further changes, since c uses only old values (for t = 0)( which are all 1. We can thus move on to k = 2  

there are no further changes for higher i (x) values. Continuing in this manner, we can produce a table of c(x) values as a function of time
