concat
concat(A, B, C, ...)
concat(A, B, C, ..., dim)
Concatenate matrices. By default, the matrices are concatenated by the last dimension. The dimension on which to concatenate can be provided as last argument.
Try it yourself:
| $1 | A = [1, 2; 5, 6]
| |
| $2 | B = [3, 4; 7, 8]
| |
| $3 | concat(A, B)
| |
| $4 | concat(A, B, 1)
| |
| $5 | concat(A, B, 2)
