A Tensor. Must be one of the following types: half, float32, float64.
Output of batch Cholesky algorithm l = cholesky(A). Shape is [..., M, M].
Algorithm depends only on lower triangular part of the innermost matrices of
this tensor.
grad
A Tensor. Must have the same type as l.
df/dl where f is some scalar function. Shape is [..., M, M].
Algorithm depends only on lower triangular part of the innermost matrices of
this tensor.
