高阶的前向差值可以通过递归的方式进行计算，目前只支持 n=1。
高阶的前向差值可以通过递归的方式进行计算，`n`的值支持任意正整数。

参数
::::::::::::

- **x** (Tensor) - 待计算前向差值的输入 `Tensor`，支持 bool、int32、int64、float16、float32、float64 数据类型。
- **n** (int，可选) - 需要计算前向差值的次数，目前仅支持 `n=1`，默认值为 1。
- **n** (int，可选) - 需要计算前向差值的次数，`n`的值支持任意正整数，默认值为 1。
- **axis** (int，可选) - 沿着哪一维度计算前向差值，默认值为-1，也即最后一个维度。
- **prepend** (Tensor，可选) - 在计算前向差值之前，沿着指定维度 axis 附加到输入 x 的前面，它的维度需要和输入一致，并且除了 axis 维外，其他维度的形状也要和输入一致，默认值为 None。
- **append** (Tensor，可选) - 在计算前向差值之前，沿着指定维度 axis 附加到输入 x 的后面，它的维度需要和输入一致，并且除了 axis 维外，其他维度的形状也要和输入一致，默认值为 None。
