tf.linalg.tensor_diag(
    diagonal,
    name=None
)

Defined in generated file: tensorflow/python/ops/gen_array_ops.py.

Returns a diagonal tensor with a given diagonal values.

Given a diagonal, this operation returns a tensor with the diagonal and everything else padded with zeros. The diagonal is computed as follows:

Assume diagonal has dimensions [D1,..., Dk], then the output is a tensor of rank 2k with dimensions [D1,..., Dk, D1,..., Dk] where:

output[i1,..., ik, i1,..., ik] = diagonal[i1, ..., ik] and 0 everywhere else.

For example:

# 'diagonal' is [1, 2, 3, 4]
tf.diag(diagonal) ==> [[1, 0, 0, 0]
                       [0, 2, 0, 0]
                       [0, 0, 3, 0]
                       [0, 0, 0, 4]]

Args:

• diagonal: A Tensor. Must be one of the following types: bfloat16, half, float32, float64, int32, int64, complex64, complex128. Rank k tensor where k is at most 1.
• name: A name for the operation (optional).

Returns:

A Tensor. Has the same type as diagonal.
