We already require all std::vector\n  objects to be correctly set up - there is no point in providing an\n  additional n_eigenvectors parameter. Drop unused \"stiffness_matrix\".\n\n * remove unnecessary switch statements and temporary variables\n\nCloses #759"},"comment":{"url":"https://api.github.com/repos/dealii/dealii/issues/comments/98460426","html_url":"https://github.com/dealii/dealii/pull/891#issuecomment-98460426","issue_url":"https://api.github.com/repos/dealii/dealii/issues/891","id":98460426,"user":{"login":"guidokanschat","id":7237526,"avatar_url":"https://avatars.githubusercontent.com/u/7237526?v=3","gravatar_id":"","url":"https://api.github.com/users/guidokanschat","html_url":"https://github.com/guidokanschat","followers_url":"https://api.github.com/users/guidokanschat/followers","following_url":"https://api.github.com/users/guidokanschat/following{/other_user}","gists_url":"https://api.github.com/users/guidokanschat/gists{/gist_id}","starred_url":"https://api.github.com/users/guidokanschat/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/guidokanschat/subscriptions","organizations_url":"https://api.github.com/users/guidokanschat/orgs","repos_url":"https://api.github.com/users/guidokanschat/repos","events_url":"https://api.github.com/users/guidokanschat/events{/privacy}","received_events_url":"https://api.github.com/users/guidokanschat/received_events","type":"User","site_admin":false},"created_at":"2015-05-03T09:30:00Z","updated_at":"2015-05-03T09:30:00Z","body":"I'm wondering a bit, why we replace a very broken interface by an incompatible broken one, which will probably have to be replaced again once we understand Arpack.
