tf.raw_ops.Diag
Returns a diagonal tensor with a given diagonal values.
tf.raw_ops.Diag( diagonal, name=None )
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]]
