diagonal() can extract the view of the 1D or more D tensor of zero or more elements on the diagonal from the 2D or more D tensor of zero or more elements as shown below:
*Memos:
diagonal()can be used withtorch or a tensor.- The 1st argument(
input) withtorchor using a tensor(Required-Type:tensorofint,float,complexorbool). - The 2nd argument with torch or the 1st argument with a tensor is
offset(Optional-Default:0-Type:int). - The 3rd argument with torch or the 2nd argument with a tensor is
dim1(Optional-Default:0-Type:int). - The 4th argument with torch or the 3rd argument with a tensor is
dim2(Optional-Default:1-Type:int).
