Web2 Nov 2016 · I had a meeting this morning so I haven't had a chance to look again. If @bmpersc says that we need to get this out today, I have an idea for a temporary work-around (just disable optimizing for multiple right-hand sides). Otherwise, I would prefer to wait and take a look, working with the code's original author, who is unavailable today. Webmultiple right-hand sides occur, for example, in applications of uncertainty quantification, where solutions for multiple perturbed right-hand sides are desired. In the above …
