This is obscure for a couple reasons.  First, it appears in a formula that was less than completely derived in the original publication.  Second, it doesn't seem to have much of an effect on the expm calculation.  But I was able to add a regression test."},"comment":{"url":"https://api.github.com/repos/scipy/scipy/issues/comments/172568755","html_url":"https://github.com/scipy/scipy/pull/4934#issuecomment-172568755","issue_url":"https://api.github.com/repos/scipy/scipy/issues/4934","id":172568755,"user":{"login":"ewmoore","id":2314641,"avatar_url":"https://avatars.githubusercontent.com/u/2314641?v=3","gravatar_id":"","url":"https://api.github.com/users/ewmoore","html_url":"https://github.com/ewmoore","followers_url":"https://api.github.com/users/ewmoore/followers","following_url":"https://api.github.com/users/ewmoore/following{/other_user}","gists_url":"https://api.github.com/users/ewmoore/gists{/gist_id}","starred_url":"https://api.github.com/users/ewmoore/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ewmoore/subscriptions","organizations_url":"https://api.github.com/users/ewmoore/orgs","repos_url":"https://api.github.com/users/ewmoore/repos","events_url":"https://api.github.com/users/ewmoore/events{/privacy}","received_events_url":"https://api.github.com/users/ewmoore/received_events","type":"User","site_admin":false},"created_at":"2016-01-18T15:55:51Z","updated_at":"2016-01-18T15:55:51Z","body":"@argriffing, is it worth taking this fix?
