* LUP decomposition
*
* Computes the LUP decomposition of a matrix or a batch of matrices.
* Given a tensor `input`, return tensors (P, L, U) satisfying `P dot input = L dot U`,
* with `P` being a permutation matrix or batch of matrices,
* Given a tensor `input`, return tensors (P, L, U) satisfying :
* `P dot input = L dot U` or `input = P dot L dot U`
* depending on the implementation, with :
* `P` being a permutation matrix or batch of matrices,
* `L` being a lower triangular matrix or batch of matrices,
* `U` being an upper triangular matrix or batch of matrices.
