本人是c++的菜鸟，向大家请教有关结构体与向量的问题：
    struct std
      {
          int id；
          vector<double> b(3);//错误，我想定义一个（x，y，z）向量的？？？  
       }sss；
我的头文件是：

#ifdef HAVE_CONFIG_H
#include <config.h>
#endif

#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string>
// #include <vector>


#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
#include <boost/numeric/ublas/triangular.hpp>

不是这样玩的，如下即可：

#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string>
#include <vector>
using std::vector;

typedef struct _DOUBLEPOINTER
{
    double X;
    double Y;
    double Z;
}DOUBLEPOINTER, *PDOUBLEPOINTER;

struct _std
{
    int id;
    vector<DOUBLEPOINTER> b;//OK
};

非常感谢你，我知道该怎么做了啊！哈哈，谢谢了！

请问怎么进行赋值呢？

#include <stdio.h>
#include <stdlib.h>
#include <iostream>
#include <string>
#include <vector>
using std::vector;

typedef struct _DOUBLEPOINTER
{
    double X;
    double Y;
    double Z;
}DOUBLEPOINTER, *PDOUBLEPOINTER;

typedef struct _std
{
    int id;
    vector<DOUBLEPOINTER> b;//OK
}MYSTD, *PMYSTD;

void main()
{
    MYSTD stData;
    DOUBLEPOINTER OnePoint = {0.1,36.72,9.188475},TwoPoint;
   
    stData.id = 1;
    stData.b.push_back(OnePoint);
    stData.b.push_back(TwoPoint);

    stData.b[1].X = 0.744;
    stData.b[1].Y = 83.1;
    stData.b[1].Z = 11.55;

    for(int i = 0; i < stData.b.size(); i ++)
    {
        printf("%f,%f,%f\n",stData.b[i].X,stData.b[i].Y,stData.b[i].Z);
    }
}
