Eigen에서 블록 작업이 작동하지 않습니다.

Question

Eigen에서 블록 작업이 작동하지 않습니다. 내가 좋아하는 오류의 무리 받고 있어요 :

error: ‘Eigen::Vector4d’ has no member named ‘head’ 

이 오류를 생성하는 코드 줄 것은 : out는 Eigen::Vector4d 및 outVector입니다

outVector.push_back(out.head<3>()); 

가 std::vector<Eigen::Vector4d>이다. 또한 거기에 아마 몇 가지 관련이없는 컴파일러 오류가있다

,하지만 난 거기에 도착했을 때 나는 그 작업을합니다 :

전체 오류 출력이다.

Answer 1

코드가 (이 start()를 불렀다) eigen2에 존재하지 않는 기능 head() 이후 eigen3을 기대하는 동안 eigen2을 사용하는 것 같다.
