I couldn't find a good reference online for the many different diagonals of a matrix, so I decided to create one. As time goes on, I will keep adding diagonals that I've missed.
The main diagonal is the diagonal of a matrix that spans from the upper left corner to the bottom right corner.
It's also referred to as:
- Principal diagonal
- Leading diagonal
The anti-diagonal is the diagonal that spans from the lower left corner to the upper right corner.
