torch.msort
torch.msort(input, *, out=None) -> Tensor
Sorts the elements of the "input" tensor along its first dimension
   in ascending order by value.
Note:
 *torch.msort(t)* is equivalent to *torch.sort(t, dim=0)[0]*. See
 also "torch.sort()".

Parameters:
      input (Tensor) -- the input tensor.
Keyword Arguments:
      out (Tensor, optional) -- the output tensor.
Example:
  >>> t = torch.randn(3, 4)
  >>> t
  tensor([[-0.1321,  0.4370, -1.2631, -1.1289],
          [-2.0527, -1.1250,  0.2275,  0.3077],
          [-0.0881, -0.1259, -0.5495,  1.0284]])
  >>> torch.msort(t)
  tensor([[-2.0527, -1.1250, -1.2631, -1.1289],
          [-0.1321, -0.1259, -0.5495,  0.3077],
          [-0.0881,  0.4370,  0.2275,  1.0284]])
