Posting the very same text again isn't going to help - those that are
reading it now are likely the same that read it before.
If nobody replied, assume that something is wrong with the question
itself. Not the grammar, looks clear to me. Maybe the meaning: you say "a
2-D array" but you don't say what that means (a list? an array.array
object? a Numpy array?).
Consider *who* might be able to answer: someone that knows both Python and
matlab, and knows how to use a sparse matrix, and knows how to read data
from files, and knows how to generate such files from Python. The last
part is the easy part, because people here is supposed to know how to do
things in Python; but not how matlab works. So, please help people help
you: tell us what file format would be fine for matlab to read, and people
here surely will suggest the best way to write that in Python.
Reading http://www.mikeash.com/getting_answers.html may help too.
