SquareDifference
=================

逐元素计算两个输入数组对应元素的差的平方。

.. math::

    \text{output}_i = (\text{input0}_i - \text{input1}_i)^2

对于输入 `input0` 和 `input1` 中对应位置的每个元素，计算它们差的平方值。

输入：
    - **input0** - 第一个输入数据地址。
    - **input1** - 第二个输入数据地址。
    - **params** - 参数打包成数组：
        - **input0_dims** - input0的维度信息数组（int*）。
        - **input1_dims** - input1的维度信息数组（int*）。
        - **output_dims** - output的维度信息数组（int*）。
        - **strides0** - input0的步长数组（int*）。
        - **strides1** - input1的步长数组（int*）。
        - **strides_output** - output的步长数组（int*）。
        - **num_dims** - 维度数（int）。
    - **core_mask** - 核掩码（仅共享存储版本需要）。
输出：
    - **output** - 计算结果地址，其大小与输入相同。

支持平台：
    ``FT78NE``
    ``MT7004``
