Whatever you do - reuse class Matrix, write your own - it is the most
reasonable thing to have a specific class for handling this instead of
writing functions which work with a nested Array structure.  It will
make your life much easier because then you Matrix class can enforce
proper internal state which you cannot as easily when using a set of
functions to manipulate an Array structure.

Kind regards
