Thats ok, thanks Matt. Just so i'm clear - if i call SNESCreate_Picard(), that will set all the other SNES functions to their _Picard equivalents, then i can just use the regular SNES function calls (without having to set the build F or build J functions) to solve my problem. This is right yeah?

It has only quadratic line search now. I can give an example of custom line search if yo want.

I'm just wondering because there seems to be some functionality in the src/snes/impls/picard directory, but there's very little documentation on any of this in the online index pages, and nothing in the version 3.0.0 manual...
