tensorflow:: ops:: MatrixDiagPart

Returns the batched diagonal part of a batched tensor.

Summary

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

Assume input has k dimensions [I, J, K, ..., M, N] , then the output is a tensor of rank k - 1 with dimensions [I, J, K, ..., min(M, N)] where:

diagonal[i, j, k, ..., n] = input[i, j, k, ..., n, n] .

The input must be at least a matrix.

For example:

# 'input' is [[[1, 0, 0, 0]
               [0, 2, 0, 0]
               [0, 0, 3, 0]
               [0, 0, 0, 4]],
              [[5, 0, 0, 0]
               [0, 6, 0, 0]
               [0, 0, 7, 0]
               [0, 0, 0, 8]]]

and input.shape = (2, 4, 4)

tf.matrix_diag_part(input) ==> [[1, 2, 3, 4], [5, 6, 7, 8]]

which has shape (2, 4)

Args:

• scope: A Scope object
• input: Rank k tensor where k >= 2 .

Returns:

• Output : The extracted diagonal(s) having shape diagonal.shape = input.shape[:-2] + [min(input.shape[-2:])] .
