`std::vector<`[`Tensor`](../Tensor.md)`>` **`broadcast_tensors`**([`ClikaRT::Span`](../Span.md)`<const` [`Tensor`](../Tensor.md)`>` `tensors`)

</div>

Broadcast every input to their common shape: dims are right-aligned, size-1 dims stretch, anything else must match.

Returns VIEWS; each output shares its input's storage, with the stretched positions aliasing ONE stored element; treat the results as read-only (or [`contiguous`](./contiguous.md#contiguous) one to materialize it).

**Throws**

- `ClikaRT::Error`: (`INVALID_ARGUMENT`) when the shapes are not broadcast-compatible (`code_name()` carries the reason).

**Returns:** one view per input, all of the common broadcast shape.
