broadcast_constant

broadcast_constant(base_array, target_shape, pad_base=False): 

LLM Docstring

Broadcast a scalar or array up to a target shape.

A scalar is filled into target_shape; an array is expanded with leading axes so it broadcasts against target_shape (with the array’s own shape appended when pad_base is set).

• base_array: float | np.ndarray

  the value to broadcast

• target_shape: tuple[int, ...]

  the desired leading shape

• pad_base: bool

  append the base array’s shape to the target shape

• :returns: np.ndarray

  the broadcast array
