class_docstr: `LinearOperator` acting like a [batch] of toeplitz matrices.
  
  This operator acts like a [batch] Toeplitz matrix `A` with shape
  `[B1,...,Bb, N, N]` for some `b >= 0`.  The first `b` indices index a
  batch member.  For every batch index `(i1,...,ib)`, `A[i1,...,ib, : :]` is
  an `N x N` matrix.  This matrix `A` is not materialized, but for
  purposes of broadcasting this shape will be relevant.
  
  #### Description in terms of toeplitz matrices
  
  Toeplitz means that `A` has constant diagonals. Hence, `A` can be generated
  with two vectors. One represents the first column of the matrix, and the
  other represents the first row.
  
  Below is a 4 x 4 example:
  
  ```
  A = |a b c d|
      |e a b c|
      |f e a b|
      |g f e a|
  ```
  
  #### Example of a Toeplitz operator.
  
  ```python
  # Create a 3 x 3 Toeplitz operator.
  col = [1., 2., 3.]
  row = [1., 4., -9.]
  operator = LinearOperatorToeplitz(col, row)
  
  operator.to_dense()
  ==> [[1., 4., -9.],
       [2., 1., 4.],
       [3., 2., 1.]]
  
  operator.shape
  ==> [3, 3]
  
  operator.log_abs_determinant()
  ==> scalar Tensor
  
  x = ... Shape [3, 4] Tensor
  operator.matmul(x)
  ==> Shape [3, 4] Tensor
  ```
  
  #### Shape compatibility
  
  This operator acts on [batch] matrix with compatible shape.
  `x` is a batch matrix with compatible shape for `matmul` and `solve` if
  
  ```
  operator.shape = [B1,...,Bb] + [N, N],  with b >= 0
  x.shape =   [C1,...,Cc] + [N, R],
  and [C1,...,Cc] broadcasts with [B1,...,Bb] to [D1,...,Dd]
  ```
  
  #### Matrix property hints
  
  This `LinearOperator` is initialized with boolean flags of the form `is_X`,
  for `X = non_singular, self_adjoint, positive_definite, square`.
  These have the following meaning:
  
  * If `is_X == True`, callers should expect the operator to have the
    property `X`.  This is a promise that should be fulfilled, but is *not* a
    runtime assert.  For example, finite floating point precision may result
    in these promises being violated.
  * If `is_X == False`, callers should expect the operator to not have `X`.
  * If `is_X == None` (the default), callers should have no expectation either
    way.
