Hello, I am in need of your help please. I have a vertical line inside a matrix that separates columns and extends from the top to the bottom. How is this best transcribed? I’ve narrowed my choices to two: the 456 indicator on each row or the braille vertical bar on each. Is one of those correct?
456 has been specified as a vertical line (in division arrangements). I would use that line for the augmented matrix. If there is a question of space, the line may be spurred.
