+## [ 组合替代实现 ]torch.copysign
+
+### [torch.copysign](https://pytorch.org/docs/stable/generated/torch.copysign.html#torch.copysign)
+
+```python
+torch.copysign(input,
+          other,
+          *,
+          out=None)
+```
+创建一个新的浮点张量，其大小与` input `相同，正负符号与` other `相同
+
+PaddlePaddle 目前无对应 API，可使用如下代码组合替代实现:
+
+### 转写示例
+
+#### out：指定输出
+```python
+# Pytorch 写法
+torch.copysign(input, other, out=y)
+
+# Paddle 写法
+paddle.assign(paddle.abs(input) * paddle.sign(other), y)
+```
