Question

Maybe it\'s just my lack of abilities to find stuff here that is the problem, but I can\'t find anything about how to create multidimensional arrays in Ruby.

It might help to remember that the array is an object in ruby, and objects are not (by default) created simply by naming them or naming a the object reference. Here is a routine for creating a 3 dimension array and dumping it to the screen for verification:

def Create3DimensionArray(x, y, z, default)
    n = 0                       # verification code only
    ar = Array.new(x)
    for i in 0...x
        ar[i] = Array.new(y)
        for j in 0...y
            ar[i][j] = Array.new(z, default)
            for k in 0...z      # verification code only
                ar[i][j][k] = n # verification code only
                n += 1          # verification code only
            end                 # verification code only
        end
    end
    return ar
end

# Create sample and verify
ar = Create3DimensionArray(3, 7, 10, 0)

for x in ar
    puts "||"
    for y in x
        puts "|"
        for z in y
            printf "%d ", z
        end
    end
end
