WebFeb 24, 2015 · L U x = b. Let us break the task into two parts: first, we find y such that. L y = b. Then,find x such that. U x = y. It is obvious by multiplying the last equation by L from the left that such x will be the solution to the original problem. Now, what makes LU - decomposition useful is that both sub-tasks can be exactly solved in one pass!
