LU-Factorization Algorithm??

Homework Statement


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.

Homework 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..

The Attempt at a Solution


I don't know how to attempt this problem.


Thanks in advance for your help! :approve:
