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,
Minkoo S.
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.
