That needs to discussed with @scheufks.\r\n* Functions like ```tarch::la::equals```\r\n\r\nStuff in that package should really concentrate on the numerics and should be independent as far as possible."},"comment":{"url":"https://api.github.com/repos/precice/precice/issues/comments/112733268","html_url":"https://github.com/precice/precice/issues/8#issuecomment-112733268","issue_url":"https://api.github.com/repos/precice/precice/issues/8","id":112733268,"user":{"login":"floli","id":1028028,"avatar_url":"https://avatars.githubusercontent.com/u/1028028?v=3","gravatar_id":"","url":"https://api.github.com/users/floli","html_url":"https://github.com/floli","followers_url":"https://api.github.com/users/floli/followers","following_url":"https://api.github.com/users/floli/following{/other_user}","gists_url":"https://api.github.com/users/floli/gists{/gist_id}","starred_url":"https://api.github.com/users/floli/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/floli/subscriptions","organizations_url":"https://api.github.com/users/floli/orgs","repos_url":"https://api.github.com/users/floli/repos","events_url":"https://api.github.com/users/floli/events{/privacy}","received_events_url":"https://api.github.com/users/floli/received_events","type":"User","site_admin":false},"created_at":"2015-06-17T09:24:43Z","updated_at":"2015-06-17T09:24:43Z","body":"For Eigen objects we would of course use the member functions.
