I read a CSV file. This file looks like this

1.00 cm; 2.00cm ; 3.00 cm; ... ; 100 cm
2.00 cm; 4.00 cm; 6.00 cm; ... ; 100 cm
4.00 cm; 8.00 cm; 12.00 cm; ... ; 100cm
8.00 cm; 16.00 cm; 24.00 cm; ... ; 100cm

I have already written the following code

CSV.foreach("/Users/testUser/Entwicklung/coverrechner/CoverPaperDE.csv", col_sep: ';') do |row|
      puts row[0]
end

This produces the following output:

1.00 cm
2.00 cm
4.00 cm
8.00 cm

Example: My matrix is constructed

1.1 1.2 1.3 1.4

2.1 2.2 2.3 2.4

3.1 3.2 3.3 3.4

4.1 4.2 4.3 4.4

I want the following output

1.1 2.1 3.1 4.1 1.2 2.2 3.2 4.2 ... 4.4

How does it work?
