我正在使用 Visual Studio 2012,我在我的代码中隔离了一个问题,但我无法解决它。在发布模式下运行它时效果很好,但如果我在调试中运行它会出错。代码是:
#include "stdafx.h"
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
typedef boost::numeric::ublas::matrix<double> BMT;
BMT fun()
{
BMT mym;
mym.resize(3,3);
for(int i = 0; i<9;++i) mym(i/3,i%3)=i;
std::cout << mym << std::endl;
return mym;
}
int main(int argc, char* argv[])
{
fun();
//closing message
std::cout<<std::endl<<"press enter to exit."<<std::endl;
std::cin.ignore( std::numeric_limits<std::streamsize>::max(), '\n' );
}
调试中的错误如下:
