matrices can be written as the product of matrices in special form

Matrix factorizations are useful mathematically and computationally:

- Mathematical: They provide insight into the nature of matrices—each factorization gives us a new way to think about a matrix.
- Computational: They give us ways to compute solutions to fundamental computational problems involving matrices.
