</div>

Kronecker product of two same-rank tensors.

Output dim `i` is `input.shape[i] * b.shape[i]`; each `input` element scales a full copy of `other` into its block.

**Parameters**

- `input`: left operand, rank `N`.
- `other`: right operand, rank `N` (same rank as `input`).

**Returns:** the rank-`N` Kronecker product.

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the ranks disagree.
