From the tutorial, http://eigen.tuxfamily.org/dox/TutorialReductionsVisitorsBroadcasting.html mat.colwise() += v; //works mat.colwise() -= v; //works mat.colwise() *= v; //not implemented mat.colwise() /= v; //not implemented Moreover, mat2 = mat.colwise() + v; //works mat2 = mat.colwise() - v; //works mat2 = mat.colwise() * v; //not implemented mat2 = mat.colwise() / v; //not implemented mat2 = v + mat.colwise(); //not implemented mat2 = v - mat.colwise(); //not implemented mat2 = v * mat.colwise(); //not implemented mat2 = v / mat.colwise(); //not implemented I think these are so fundamental operators so I rated 'critical'.
Somebody already reported, I'll add this to that as a comment. *** This bug has been marked as a duplicate of bug 157 ***
