为什么这行得通?它不在任何地方的文档中...
#include <iostream>
#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
int main()
{
boost::numeric::ublas::matrix<double> twoByTwoMat(2,2,-2);
std::cout << "This is the matrix: " << twoByTwoMat << std::endl;
return 0;
}
输出:
This is the matrix: [2,2]((-2,-2),(-2,-2))
