C++ Boost库 uBLAS 笔记

构造

Vector

 1 #include <boost/numeric/ublas/vector.hpp>
 2 #include <boost/numeric/ublas/io.hpp>
 3 
 4 int main () {
 5     using namespace boost::numeric::ublas;
 6     vector<double> v (3);
 7     for (unsigned i = 0; i < v.size (); ++ i)
 8         v (i) = i;
 9     std::cout << v << std::endl;
10 }

 

Matrix

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

int main () {
    using namespace boost::numeric::ublas;
    matrix<double> m (3, 3);
    for (unsigned i = 0; i < m.size1 (); ++ i)
        for (unsigned j = 0; j < m.size2 (); ++ j)
            m (i, j) = 3 * i + j;
    std::cout << m << std::endl;
}
