Another use case, typically, is to factor once and use it I on multiple right hand sides for linear equations. You might not yet have access to the right hand side but don't want to pay decomposition cost each time for Ax = b1 Ax = b2 And so on. Basically a quick hack to accommodate the use case with a low-level function instead of providing a cached operator, done in the very early times. In hindsight it's easy to criticize but it filled an important void for quite some time. On Tue, Apr 25, 2023, 02:08 Jake Bowhay <jb9.bowhay@gmail.com> wrote:
