It's really hard to say in what way I don't understand something that I'm not sure I even understand.

I think one approach is to maybe fully explain the column major approach, and then introduce the row major approach, and lastly how those two interact.

> [1 2; 3 4]` is equivalent to `[1; 3;; 2; 4]`.

is a hard to understand example.

Is the space equal to ;;? e.g., is [1 2; 3 4] the same as [1;;2;3;;4]?
