What is the advantage to having the LU factorization of a matrix?

However, LU-factorization has the following advantages: Gaussian elimination and Gauss--Jordan elimination both use the augmented matrix [A|b], so b must be known. In contrast, LU-decomposition uses only matrix A, so once that factorization is complete, it can be applied to any vector b.

How do you find the LU value of a matrix?

For the upper triangular matrix all theMoreAnd all elements above the main diagonal must be zero. For the upper triangular matrix all the elements below the main diagonal must be zero. Notice for the upper triangular matrix the main diagonal.

Does LU decomposition always work?

This implies that for a square matrix: LUP always exists (We can use this to quickly figure out the determinant). If the matrix is invertible (the determinant is not 0), then a pure LU decomposition exists only if the leading principal minors are not 0.

Why do we need matrix decomposition?

Many complex matrix operations cannot be solved efficiently or with stability using the limited precision of computers. Matrix decompositions are methods that reduce a matrix into constituent parts that make it easier to calculate more complex matrix operations.

What is LU factorization used for?

LU decomposition is a better way to implement Gauss elimination, especially for repeated solving a number of equations with the same left-hand side. That is, for solving the equation Ax = b with different values of b for the same A.
