Once the factorization is done, the factors will be used in every iteration. The convenience of having A factored as LtUt is that the system Ax = b can be solved instead as LtUtx = b in two passes: First, by finding the vector y such that Lty = b, then by solving Utx = y.

(For example 0+x = x and does not require an actual addition). For example in Matlab when a matrix is identified as a “sparse” matrix, Matlab will use a different algorithm to solve Ax = b than if the matrix is “full” (that is mostly nonzero). The different algorithm will take advantage of the zeros in A, if possible.

Jan 20, 2009 · If the rank of the original matrix, A, equals the rank of the augmented matrix, [A,b], but is less than the number of unknowns, m, there are an infinite number of solutions to the matrix equation, Ax = b. If the rank of the original matrix, A, is not equal the rank of the augmented matrix, [A,b], there is no solution to the matrix equation, Ax = b.
