One more thing - I forgot that I need to get the result back to a string... So (thanks to your help andn Ruby's 'eval') I can go from this:

"{{3.1, 1.3, 2.5, 2.1}, {2.1, 3.1, 2.4, 2.2}, {1.4, 2.2, 2.1, 4.2}}"

to this:

[[1.4, 2.2, 2.1, 4.2], [2.1, 3.1, 2.4, 2.2], [3.1, 1.3, 2.5, 2.1]]

but I can't persuade the 'p' method to turn this back into a string:

Kernel#p actually prints stuff, using #inspect rather than #to_s. So,
my_array.inspect will give you the below String.

"[[1.4, 2.2, 2.1, 4.2], [2.1, 3.1, 2.4, 2.2], [3.1, 1.3, 2.5, 2.1]]"

(and I should be able to go from here to :

"{{1.4, 2.2, 2.1, 4.2}, {2.1, 3.1, 2.4, 2.2}, {3.1, 1.3, 2.5, 2.1}}"

on my own :-)

Yep, just do the exact inverse of how you got the normal Array syntax.
Why do you need to translate it back to the same form, though?
