A.8 Complex Data Structures

The standard Perl data types, scalar,
array, and hash, can be combined into more complex data structures
using references. The construction of complex data structures is
summarized in Chapter 2.

As an example, you can define a two-dimensional matrix as an array of
anonymous arrays (recall that an anonymous array is a reference to
array data):

@microarray = (
[ 10, 2, 14 ],
[ 15, 4, 54 ],
[ 51, 0, 99 ]
);
