Construct a matrix from labelled information or an entry rule
The table records the points scored by each player in each round. Use the row labels and column labels to construct the matrix \(B\)
| Player / Round | Round 2 | Round 1 | Round 3 |
|---|---|---|---|
| Bella | 7 | 5 | 7 |
| Ari | 6 | 5 | 3 |
For the required matrix, rows are ordered as Ari, Bella and columns are ordered as Round 3, Round 2, Round 1. The category labels are headings, not numerical entries
