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, L being a lower triangular matrix or batch of matrices, U being an upper triangular matrix or batch of matrices.
Receiver
the input.
Return
triple of P, L and U tensors
