如何从两个向量（real& imag）获得复数向量 [英] How to get Vector of Complex numbers from two vectors (real & imag)

问题描述

我有两个浮点向量，我希望它们成为复数的一个向量。我被卡住了。我不介意使用迭代器，但是我敢肯定它将重新发现我不知道的轮子。

I have two vectors of floats and i want them to become one vector of Complex numbers. I'm stuck. I don't mind using iterators, but i am sure it'd be rediscovering the wheel i'm not informed about. Is my code leading me in the right direction?

typedef std::vector<float> CVFloat;
CVFloat vA, vB;
//fil vectors
typedef std::complex<CVFloat> myComplexVector;
myComplexVector* vA_Complex = new myComplexVector(vA, vB);

上面的代码正确地通过了编译器，但是当我想使用以下方式从myComplexVector中获取单个数字时迭代器我收到错误未定义符号'const_iterator'（Borland C ++）

The code above is going through the compiler correctly, but when i want to get single numbers from myComplexVector using iterator i get error "Undefined symbol 'const_iterator'" (Borland C++)

myComplexVector::const_iterator it = vA_Complex->begin();

推荐答案

此处您要创建一个复杂对象，其实际

也许您真正想做的是创建一个复杂对象的向量，这些对象的实部和虚部都是浮点数？

Here you are creating a "complex" object whose real and imaginary parts are vectors of floats.
Maybe what you actually want to do is creating a vector of complex objects whose real and imaginary parts are floats?

编辑：myComplexVector不是向量，是复杂的。这就是为什么未定义 const_iterator 的原因。

myComplexVector is not a vector, is a complex. That's why a const_iterator for it is not defined.
