Matrix in Ruby

What is the best way to create a matrix whose size is m x n?
The value of m and n may be different, and the values in each cell
should be zeroed.

Can anybody help me?

Sincerely,

I've found it by myself:

a = Matrix[(0..3).map { Array.new(5) }]

if you're going to be working with large matrices and doing lots of number
crunching you'll want

   require 'narray'

   a = NArray.int 3, 5

it's on the raa.

cheers.
