C++ 用模板增强随机性

所以我尝试使用Boost.Random mt19937生成器和模板。我的C++有点生疏，但是从我所理解的（和文档一样，总是为Boost，不小于模糊），它应该采取模板参数，指定它的返回类型（浮点/ double）。 我现在不知道问题在哪里。。。它全部使用

或

工作，并停止使用模板

代码如下：

template <class T>
class SpikingMatrixHelper {
public:
    SpikingMatrixHelper(const int seed);
    T generateNumber(const T, const T) const;
private:
    boost::mt19937 gen;
};

template <class T>
SpikingMatrixHelper<T>::SpikingMatrixHelper(const int seed) : gen(seed) {}

template <class T>
T SpikingMatrixHelper<T>::generateNumber(const T min, const T max) const {
    boost::uniform_real<T> dist(min, max);
    boost::variate_generator<boost::mt19937&, boost::uniform_real<T> > g(gen, dist);
    return g();
}

正如我所说，自从我完成C++以来，已经有一段时间了，Boost DOC留下了许多值得索取的东西，所以任何提示都值得欣赏……< /P> < P>代码> GuangNo.No/<代码>不能是代码> const ——它置换了MelShanne Wistor。使该

模板编译器错误！=可读信息-容易错过
