A generalized ellipsoid doesn't have a configuration matrix in a common sense (by construction) but it does have\r\na) a basis in L and its complement.\r\nb) a configuration matrix of E (ellipsoid in the orthogonal complement to L). \r\n\r\nYou will have to refer to the generalized ellipsoid class implementation (elltool.core.GenEllipsoid class)\r\nand its tests in \r\n\r\n\t\telltool.core.test.mlunit.GenEllipsoidTestCase\r\n\t\telltool.core.test.mlunit.GenEllipsoidPlotTestCase\r\n\r\nfor a better understanding of how this class works.\r\n\r\nOnce you gain a sufficient level of confidence in your understanding of GenEllipsoid class please \r\nimplement the following methods of ellipsoid class in GenEllipsoid class. \r\nMethod names, format of input and output arguments should not be changed. \r\n\r\nisbigger\r\ntrace\r\nshape\r\ngetShape\r\nmtimes\r\nparameters\r\nplus\r\nminus\r\npolar\r\nprojection\r\nfromRepMat\r\nvolume\r\nmaxeig\r\nmineig\r\nempty\r\ntrace\r\ntoStruct\r\nhpintersect\r\n\r\n\r\nAll these methods should be covered with all kinds of tests that you need to put into \r\nelltool.core.test.mlunit.GenEllipsoidSecTC class.
