luFactor
fun DoubleTensorAlgebra.luFactor(structureND: StructureND<Double>, epsilon: Double = 1.0E-9): Pair<DoubleTensor, IntTensor>(source)
Computes the LU factorization of a matrix or batches of matrices input. Returns a tuple containing the LU factorization and pivots of input.
Return
pair of factorization and pivots. The factorization has the shape `(*, m, n)`, where`(*, m, n)` is the shape of the input tensor. The pivots has the shape `(∗, min(m, n))`. pivots stores all the intermediate transpositions of rows.
Parameters
epsilon
permissible error when comparing the determinant of a matrix with zero default is 1e-9
