how to create a 2 x 3 matrix in apl? in ruby

To create a 2 x 3 matrix in APL, you can use the following code:

main.rb
⍝ Declare a 2 x 3 matrix
matrix ← 2 3 ⍴ ⍳6
43 chars
3 lines

This code creates a range of numbers from 1 to 6 (⍳6) and reshapes it into a 2 x 3 matrix using the ⍴ operator.

In Ruby, you can create a 2 x 3 matrix using the Matrix class from the matrix library:

main.rb
require 'matrix'

# Create a 2 x 3 matrix
matrix = Matrix[[1, 2, 3], [4, 5, 6]]
80 chars
5 lines

Here, we use the Matrix class and provide a nested array containing the elements of the matrix.

Please note that APL code uses APL specific operators and syntax, while Ruby code uses Ruby-specific classes and syntax.
