Frequently Asked Questions
When is LU factorization useful?
LU factorization is particularly useful when solving multiple linear systems with the same coefficient matrix but different right-hand sides.
What are the limitations?
LU factorization requires the matrix to be nonsingular and may need pivoting for numerical stability.
How does it compare to other methods?
LU factorization is more efficient than Gaussian elimination when solving multiple systems and provides additional insights into matrix properties.
