C++ Boost库 uBLAS 笔记

构造

Vector

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

 int main () {
     using namespace boost::numeric::ublas;
     vector<double> v ();
     for (unsigned i = ; i < v.size (); ++ i)
         v (i) = i;
     std::cout << v << std::endl;
 }

Matrix

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

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