# torch.cross

torch.cross(input, other, dim=None, *, out=None) → Tensor

  Returns the cross product of vectors in dimension `dim` of `input` and `other`.

  Supports input of float, double, cfloat and cdouble dtypes. Also supports batches of vectors, for which it computes the product along the dimension `dim`. In this case, the output has the same batch dimensions as the inputs.

  If `dim` is not given, it defaults to the first dimension found with the size 3. Note that this might be unexpected.

  See also

  `torch.linalg.cross()` which requires specifying dim (defaulting to -1).

  Warning

  This function may change in a future PyTorch release to match the default behaviour in `torch.linalg.cross()`. We recommend using `torch.linalg.cross()`.

  Parameters:

    - input (Tensor) – the input tensor.

    - other (Tensor) – the second input tensor

    - dim (int, optional) – the dimension to take the cross-product in.

  Keyword Arguments:

    out (Tensor, optional) – the output tensor.

  Example:

      >>> a = torch.randn(4, 3)
      >>> a
      tensor([[-0.3956,  1.1455,  1.6895],
              [-0.5849,  1.3672,  0.3599],
              [-1.1626,  0.7180, -0.0521],
              [-0.1339,  0.9902, -2.0225]])
      >>> b = torch.randn(4, 3)
      >>> b
      tensor([[-0.0257, -1.4725, -1.2251],
              [-1.1479, -0.7005, -1.9757],
              [-1.3904,  0.3726, -1.1836],
              [-0.9688, -0.7153,  0.2159]])
      >>> torch.cross(a, b, dim=1)
      tensor([[ 1.0844, -0.5281,  0.6120],
              [-2.4490, -1.5687,  1.9792],
              [-0.8304, -1.3037,  0.5650],
              [-1.2329,  1.9883,  1.0551]])
      >>> torch.cross(a, b)
      tensor([[ 1.0844, -0.5281,  0.6120],
              [-2.4490, -1.5687,  1.9792],
              [-0.8304, -1.3037,  0.5650],
              [-1.2329,  1.9883,  1.0551]])
