Examples
m=(1..15).reshape(3:5)
m;
col1 | col2 | col3 | col4 | col5 |
---|---|---|---|---|
1 | 4 | 7 | 10 | 13 |
2 | 5 | 8 | 11 | 14 |
3 | 6 | 9 | 12 | 15 |
// obtain the two elements at [0,1] and [0,2]
cells(m, 0 0, 1 2)
// output
[4,7]
// obtain the elements on the diagonal of the matrix
index = 0..2
cells(m, index, index)
// output
[1, 5, 9]
