I need  to shelve this work for a couple of days at least so I'm going to leave this PR here as a work  in progress unless Matthew wants me to merge it with his deim experiments. Here are the things I see that need thought/work on this branch.\r\n\r\n- [ ] Decide on notation: our U is Sorenson's V, Sorenson's U is the reduced based for F, our u is the unknown\r\n- [ ] Optimize loops for calculating U^t J U (this is just to speed  up our planned sensitivity studies), current implementation is just a pure python prototype.\r\n- [ ] Add DEIM to calculation P and modify F and J calculations (still using full F  and J at first)\r\n- [ ] Modify F and J API to allow efficient computation of U (P^t U)^-1 P^t F and U (P^t U)^-1 P^t J U "},"comment":{"url":"https://api.github.com/repos/erdc-cm/proteus/issues/comments/109301699","html_url":"https://github.com/erdc-cm/proteus/pull/171#issuecomment-109301699","issue_url":"https://api.github.com/repos/erdc-cm/proteus/issues/171","id":109301699,"user":{"login":"cekees","id":613654,"avatar_url":"https://avatars.githubusercontent.com/u/613654?v=3","gravatar_id":"","url":"https://api.github.com/users/cekees","html_url":"https://github.com/cekees","followers_url":"https://api.github.com/users/cekees/followers","following_url":"https://api.github.com/users/cekees/following{/other_user}","gists_url":"https://api.github.com/users/cekees/gists{/gist_id}","starred_url":"https://api.github.com/users/cekees/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/cekees/subscriptions","organizations_url":"https://api.github.com/users/cekees/orgs","repos_url":"https://api.github.com/users/cekees/repos","events_url":"https://api.github.com/users/cekees/events{/privacy}","received_events_url":"https://api.github.com/users/cekees/received_events","type":"User","site_admin":false},"created_at":"2015-06-05T13:56:56Z","updated_at":"2015-06-05T13:56:56Z","body":"@mfarthin this is ready to merge as far as I'm concerned"}}
