tensorflow::ops::DiagPart

#include <array_ops.h>

Returns the diagonal part of the tensor.

Summary

This operation returns a tensor with the diagonal part of the input. The diagonal part is computed as follows:

Assume input has dimensions [D1,..., Dk, D1,..., Dk], then the output is a tensor of rank k with 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] ```
