comment Solving matrix PDE with a range of free parameters
You're welcome, this was fun. I've made a few changes to my answer since I had the arguments to the ParametricFunction reversed.

comment Update or Animate an ArrayPlot or MatrixPlot?
@Veena right, this is why i chose that particular x Cos[x] function, so that there were no jumps in the function. I'm not sure what you can do if your data don't line up, and you require a smooth transition across boundaries.

comment Trying to model a system of differential equations for outbreaks
@xCanaan You're welcome. For a lark, you might want to plot p[t] (which you can get by summing the solutions $s(t) + e(t) + i(t) + r(t)$ just to make sure that the quantity is conserved. It should (numerically) be a horizontal line. Significant deviations would indicate that you need to change methods, e.g. use Method -> "BDF" For some particular parameters and infectious disease models, the equations are remarkably stiff.

comment How can I make a smoothed 3D plot from a list of data?
The answer of how to interpolate/smooth unstructured data is rather involved. I think for this data set you could use kriging...

Please leave the file on your Dropbox account for a long time, so that when people come to visit this question years from now, the data are still there.
