comment Can RecurrenceTable make use of CompiledFunction?
@OleksandrR. It works. Why don't you state that as an answer? It is precisely what I've been looking for! :O

comment Avoiding MainEvaluate in a CompiledFunction to fetch global variables
I know, thanks. I usually use longer names for variables, but just this time I gave in to laziness.

comment Are there guidelines for avoiding the unpacking of a packed array?
@Yu-SungChang Where can I find further information about your statement? E.g., does FoldList internally call Dimensions or does it truly unpack packed arrays? - Does this warrant its own question?

comment Tridiagonal symmetric matrix eigenvalue using bisection
@ruebenko, I hadn't thought about that! Thanks! What's surprising, however, is that numeig unpacks! And it seems it's because FoldList unpacks! This does not look nice.

comment What's the most “functional” way to do Cholesky decomposition?
@Mr.Wizard Well, I've been using Mathematica for little more than a year, so I guess it depends on your definition of "beginning user". :D Anyway, I probably will not test it on matrices larger than 20 x 20, so I realize my concern might be moot. Thank you!

It indeed looks better, but wouldn't Append make it actually run slower than the procedural approach?

comment What's the most “functional” way to do Cholesky decomposition?
Thanks for welcoming me! Anyway, I am aware of the existence of the built-in function and I have used it to test results for both implementations, but for my Computational Physics course I have to implement a Cholesky decomposition by myself. I am free to do it in whatever programming language I want, so I picked Mathematica since it is the one I am most familiar with. I know that the procedural implementation would be more than enough for my course, but I'm trying to learn functional programming as well by myself in the meanwhile. :)
