def atomic_min(x, y):
"""Atomically compute the minimum of `x` and `y`, element-wise.
Store the result in `x`, and return the old value of `x`.
`x` must be a writable target, constant expressions or scalars
are not allowed.
Args:
x, y (Union[:mod:`~taichi.types.primitive_types`, :class:`~taichi.Matrix`]): \
The input.
Returns:
The old value of `x`.
Example::
>>> @ti.kernel
>>> def test():
>>> x = 2
>>> y = 1
>>> z = ti.atomic_min(x, y)
>>> print(x) # 1 the new value of x
>>> print(z) # 2, the old value of x
>>>
>>> ti.atomic_min(1, x) # will raise TaichiSyntaxError
