Factorial number system. In combinatorics, the factorial number system, also called factoradic, is a mixed radix numeral system adapted to numbering permutations. It is also called factorial base, although factorials do not function as base, but as place value of digits.
An LU factorization refers to the factorization of A, with proper row and/or column orderings or permutations, into two factors, a unit lower triangular matrix L and an upper triangular matrix U, =, In the lower triangular matrix all elements above the diagonal are zero, in the upper triangular matrix, all the elements below the diagonal are zero.
