=head1 DESCRIPTION |
34
|
|
|
|
|
|
|
|
35
|
|
|
|
|
|
|
This is a general purpose matrix object for dealing with row+column |
36
|
|
|
|
|
|
|
data which is typical when enumerating all the pairwise combinations |
37
|
|
|
|
|
|
|
and desiring to get slices of the data. |
38
|
|
|
|
|
|
|
|
39
|
|
|
|
|
|
|
Data can be accessed by column and row names or indexes. Matrix |
40
|
|
|
|
|
|
|
indexes start at 0. |
