LU-Factorization Algorithm?? 1. The problem statement, all variables and given/known data Develop an algorithm for finding directly the UL-factorization of a matrix A, where L is a unit lower triangular and U is upper triangular. Give an algorithm for solving ULx=b. 2. Relevant equations I'm not sure how to tackle this problem since the book already showed us how to do Doolittle's factorization and I'm assuming they want a different method of doing the same thing.. 3. The attempt at a solution I don't know how to attempt this problem. Thanks in advance for your help!
