* To factor the n by n matrix A = (A(I,J)) into the product of the* lower triangular matrix L = (L(I,J)) and U = (U(I,J)), that is* A = LU, where the main diagonal of either L or U consists of all ones:** INPUT: dimension n; the entries A(I,J), 1<=I, J<=n, of A;* the diagonal L(1,1), ..., L(N,N) of L or the diagonal* U(1,1), ..., U(N,N) of U.** OUTPUT: the entries L(I,J), 1<=J<=I, 1<=I<=n of L and the entries
