def sparse_matrix_ordering_amd(input, name=None):
  r"""Computes the Approximate Minimum Degree (AMD) ordering of `input`.

Computes the Approximate Minimum Degree (AMD) ordering for a sparse matrix.

The returned permutation may be used to permute the rows and columns of the
  given sparse matrix. This typically results in permuted sparse matrix's sparse
  Cholesky (or other decompositions) in having fewer zero fill-in compared to
  decomposition of the original matrix.

The input sparse matrix may have rank 2 or rank 3. The output Tensor,
  representing would then have rank 1 or 2 respectively, with the same batch
  shape as the input.

Each component of the input sparse matrix must represent a square symmetric
  matrix; only the lower triangular part of the matrix is read. The values of the
  sparse matrix does not affect the returned permutation, only the sparsity
  pattern of the sparse matrix is used. Hence, a single AMD ordering may be
  reused for the Cholesky decompositions of sparse matrices with the same sparsity
  pattern but with possibly different values.

Each batch component of the output permutation represents a permutation of `N`
  elements, where the input sparse matrix components each have `N` rows. That is,
  the component contains each of the integers `{0, .. N-1}` exactly once. The
  `i`th element represents the row index that the `i`th row maps to.

Usage example:

```python
      from tensorflow.python.ops.linalg.sparse import sparse_csr_matrix_ops

a_indices = np.array([[0, 0], [1, 1], [2, 1], [2, 2], [3, 3]])

def sparse_matrix_sparse_cholesky(input, permutation, type, name=None):
  r"""Computes the sparse Cholesky decomposition of `input`.

Computes the Sparse Cholesky decomposition of a sparse matrix, with the given
  fill-in reducing permutation.

The input sparse matrix and the fill-in reducing permutation `permutation` must
  have compatible shapes. If the sparse matrix has rank 3; with the batch
  dimension `B`, then the `permutation` must be of rank 2; with the same batch
  dimension `B`. There is no support for broadcasting.

Furthermore, each component vector of `permutation` must be of length `N`,
  containing each of the integers {0, 1, ..., N - 1} exactly once, where `N` is
  the number of rows of each component of the sparse matrix.

Each component of the input sparse matrix must represent a symmetric positive
  definite (SPD) matrix; although only the lower triangular part of the matrix is
  read. If any individual component is not SPD, then an InvalidArgument error is
  thrown.

The returned sparse matrix has the same dense shape as the input sparse matrix.
  For each component `A` of the input sparse matrix, the corresponding output
  sparse matrix represents `L`, the lower triangular Cholesky factor satisfying
  the following identity:

```
    A = L * Lt
  ```

where Lt denotes the transpose of L (or its conjugate transpose, if `type` is
  `complex64` or `complex128`).

The `type` parameter denotes the type of the matrix elements. The supported
  types are: `float32`, `float64`, `complex64` and `complex128`.

Performs a matrix multiplication of a sparse matrix `a` with a sparse matrix

Each matrix may be transposed or adjointed (conjugated and transposed)
  according to the Boolean parameters `transpose_a`, `adjoint_a`, `transpose_b`
  and `adjoint_b`. At most one of `transpose_a` or `adjoint_a` may be True.
  Similarly, at most one of `transpose_b` or `adjoint_b` may be True.

The inputs must have compatible shapes. That is, the inner dimension of `a`
  must be equal to the outer dimension of `b`. This requirement is adjusted
  according to whether either `a` or `b` is transposed or adjointed.

The `type` parameter denotes the type of the matrix elements. Both `a` and `b`
  must have the same type. The supported types are: `float32`, `float64`,
  `complex64` and `complex128`.

Both `a` and `b` must have the same rank. Broadcasting is not supported. If they
