Flatten an array.
The axes flattened will be between ``start_axis`` and ``end_axis``,
inclusive. Negative axes are supported. After converting negative axis to
positive, axes outside the valid range will be clamped to a valid value,
``start_axis`` to ``0`` and ``end_axis`` to ``ndim - 1``.
Args:
a (array): Input array.
start_axis (int, optional): The first dimension to flatten. Defaults to ``0``.
