I do not know of a sparse approximate inverse implementation that does. (Unless you have seen a paper saying that it works well for a problem close to yours, I wouldn't worry too much. I have yet to run into a problem for which sparse approximate inverse was the best preconditioner.) -------------- next part -------------- An HTML attachment was scrubbed...
