  To store the matrices, Hama use a [http://hadoop.apache.org/hbase/ Hbase] -- Matrices are
basically tables. They are ways of storing numbers and other things. Typical matrix has rows
and columns  which is often called a 2-way matrix because it has two dimensions. For example,
you might have respondents-by-attitudes. Of course, you might collect the same data on the
same people at 5 points in time. In that case, you either have 5 different 2-way matrices,
or you could think of it as a 3-way matrix, that is respondent-by-attitude-by-time.
