我在blitz ++,armadillo,boost :: MultiArray之间用以下代码进行了比较(借用旧帖子)

#include <iostream>
using namespace std;
#include <windows.h>
#define _SCL_SECURE_NO_WARNINGS
#define BOOST_DISABLE_ASSERTS 
#include <boost/multi_array.hpp>
#include <blitz/array.h>
#include <armadillo>

int main(int argc, char* argv[])
{
    const int X_SIZE = 1000;
    const int Y_SIZE = 1000;
    const int ITERATIONS = 100;
    unsigned int startTime = 0;
    unsigned int endTime = 0;

    // Create the boost array


    //------------------Measure boost Loop------------------------------------------
    {
        typedef boost::multi_array<double, 2> ImageArrayType;
        ImageArrayType boostMatrix(boost::extents[X_SIZE][Y_SIZE]);
        startTime = ::GetTickCount();
        for (int i = 0; i < ITERATIONS; …

我试着boost::bind用std::vector<>::resize.

但是以下代码将无法编译:

#include <boost/bind.hpp>
#include <vector>
using namespace boost;

int main(){
    typedef std::vector<double> type;
    type a;
    bind(&type::resize, _1, 2)(a);
    return 0;
}

那么,我该怎么做呢？

谢谢!

提升版本1.53 gcc版本4.8或4.6

*编辑:*上面的代码适用于-std = c ++ 11.事实上,我原来的问题是:

#include <boost/bind.hpp>
#include <blitz/array.h>
#include <vector>
using namespace boost;
using namespace blitz;

int main(){
    typedef Array<double, 1> type;
    type a;
            //a.resize(4) is ok;
    bind(&type::resize, _1, 2)(a);
    return 0;
}

我的编译命令是:g ++ t.cpp -I path/include/-std = c ++ 11 -L path/lib/-l blitz
