Precisely the same trouble in subsequent factorization steps may be eliminated precisely the same way; see The fundamental treatment under. LU factorization with partial pivoting[edit] If a square, invertible matrix has an LDU (factorization with all diagonal entries of L and U equivalent to one), then the factorization is http://thongs-for-men96.pointblog.net/Not-known-Factual-Statements-About-how-t-u-an-l-b-d-32249069
