Ruby Language Multidimensional Arrays Initializing a 2D array
Example
Let's first recap how to initialize a 1D ruby array of integers:
my_array = [1, 1, 2, 3, 5, 8, 13]
Being a 2D array simply an array of arrays, you can initialize it like this:
my_array = [
[1, 1, 2, 3, 5, 8, 13],
[1, 4, 9, 16, 25, 36, 49, 64, 81],
[2, 3, 5, 7, 11, 13, 17]
]
