C ++模板typedef - C++ template typedef

問題：

I have a class 我有一堂課

template<size_t N, size_t M>
class Matrix {
    // ....
};

I want to make a typedef which creates a Vector (column vector) which is equivalent to a Matrix with sizes N and 1. Something like that: 我想做一個typedef來創建一個Vector （列向量），它等效於大小為N和1的Matrix 。

typedef Matrix<N,1> Vector<N>;

Which produces compile error. 產生編譯錯誤。 The following creates something similar, but not exactly what I want: 以下創建類似的東西，但不完全是我想要的東西：

template <size_t N>
class Vector: public Matrix<N,1>
{ };

Is there a solution or a not too expensive workaround / best-practice for it? 是否有解決方案或不太昂貴的解決方法/最佳實踐？
