luPivot

Unpacks the data and pivots from a LU factorization of a tensor. Given a tensor luTensor, return tensors Triple(P, L, U) satisfying P dot luTensor = 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.

Return

triple of P, L and U tensors

Parameters

luTensor

the packed LU factorization data

pivotsTensor
