Question 5:

I gave one answer in an earlier post, but given that it looks like you
want s to be a vector, perhaps you prefer the following (which will
work in older versions of Mathematica too) :


So in summary, you call you function with 2 arguments: a list and the
x argument. You can now refer to the entire list on the right hand
side by using s, and you can refer to the individual parts of the list
using a,b,c...

Personally, I would limit the use of 'structs' (as suggested in other
posts) to things which have some meaning together and will be used in
multiple functions. For example, I use ymd[year,month,day] to
represent dates, as I don't like the way Mathematica 6 represents them
using lists. I then wrote my own date arithmetic functions referring
to ymd[...] (the Mathematica date arithmetic functions are very slow
if you have a lot of dates)
