comment How can Private functions be made completely opaque?
The way I understood the OP's question, "The trick is not to use the Private context" in the other package is the right answer here. +1

comment large matrix eigenvalue problem
@hsxie Of course if you could refit your problem for C or Fortran, then (C)LAPACK would most probably be both faster and more economic memorywise to calculate eigenvalues. I recently ran such code and it quite easily solved matrices of size (2^15)*(2^15), requiring around 16GB memory. 2^16 would need ~60GB, and it failed on a machine with 70GB. Needless to say, I did all the prototyping in Mathematica.

comment Non linear equation phase space
NDSolve cannot numerically integrate the system of equations since at this point r0 and u0 don't have numerical values. You have to wrap Table[..., {r0, ...}, {u0, ...}] around NDSolve instead of the plot curves!

comment Using RSolve correctly
If you run your code, the returned error ("...the given boundary conditions lead to an empty solution.") is pretty helpful.

comment How can I format a table to look nice?
Just a note: TableView is notoriously unstable, you can easily crash the kernel fiddling with it, e.g. by editing a field. Until better integration (making it a proper, documented built-in) I wouldn't recommend using it.
