argsort¶

dragon.argsort(
  inputs,
  axis=- 1,
  descending=False,
  **kwargs
)[source]¶

Return the index of sorted elements along the given axis.

axis could be negative:

x = dragon.constant([[1, 2, 3], [3, 2, 1]])
index1 = dragon.argsort(x, axis=1)
index2 = dragon.argsort(x, axis=-1)  # Equivalent

Use descending to sort in the inverse order:

x = dragon.constant([1, 2, 3])
index1 = dragon.argsort(-x, descending=False)
index2 = dragon.argsort(x, descending=True)  # Equivalent

Parameters:

• inputs (dragon.Tensor) – The input tensor.
• axis (int, optional, default=-1) – The axis to sort elements.
• descending (bool, optional, default=False) – Sort in the descending order or not.

Returns:

dragon.Tensor – The output tensor.
