Welcome to the forum, fpghost!
This is C, we do everything we can imagine, damn near!
Looks to me like you want to read in some floating point numbers from a file, into an array[] of doubles.
Why not run through a bit of the C tutorial (link is in the C Tutorial tab at the top of the forum), and get familiar with some C basics.
Then get started, and post back if and when you have a problem. We are a bit of indentation nuts, so please, use [code] tags around your code and indent just as if you were totally sane, even though that may not otherwise be proven.
