Subject: Re: Multi-dimensional (like 2) arrays in Ruby

All of the replies say the same thing -- this is good.
My learning project for Ruby is implementing a turning grille cipher. I want to allocate a n*m matrix where n and m are read from stdin.

I have the n[] (the rows) array, no sweat.  But the m part (the columns) is rather elusive.

Here's my latest code:

@m = Array.new(@rows)
@M = @m.each {|row| @m[row] = Array.new(@cols)}

It doesn't work, either... :-(
