DiagPart

tensorflow C++ API

tensorflow::ops::DiagPart

Returns the diagonal part of the tensor.

Summary

This operation returns a tensor with thediagonalpart of theinput. Thediagonalpart is computed as follows:

Assumeinputhas dimensions[D1,..., Dk, D1,..., Dk], then the output is a tensor of rankkwith dimensions[D1,..., Dk]where:

diagonal[i1,..., ik] = input[i1, ..., ik, i1,..., ik].

For example:

``` 'input' is [[1, 0, 0, 0]

[0, 2, 0, 0] [0, 0, 3, 0] [0, 0, 0, 4]]

tf.diag_part(input) ==> [1, 2, 3, 4] ```

Arguments:

• scope: A Scope object
• input: Rank k tensor where k is 2, 4, or 6.

Returns:

• Output: The extracted diagonal.

Argument:

• Scope scope : A Scope object (A scope is generated automatically each page. A scope is not connected.)
• Input input: ATensor . Must be one of the following types: float32 ,float64 ,int32 ,int64 ,complex64 ,complex128 . Rank k tensor where k is 2, 4, or 6.

Return:

• Output output : Output object of Diag class object.

Result:

• std::vector(Tensor) result_output : Assume inputhas dimensions [D1,..., Dk, D1,..., Dk] , then the output is a tensor of rank k with dimensions [D1,..., Dk]
