c++ - BOOST block_prod 矩阵乘法

Question

代码是

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

using namespace boost::numeric::ublas;

int main () {

    boost::numeric::ublas::matrix<double> m (1000, 1000);
    boost::numeric::ublas::matrix<double> n (1000, 1000);
    boost::numeric::ublas::matrix<double> mn (1000, 1000);

    for (unsigned i = 0; i < m.size1 (); ++ i)
        for (unsigned j = 0; j < m.size2 (); ++ j)
            m (i, j) = 3 * i + j;

    for (unsigned i = 0; i < n.size1 (); ++ i)
        for (unsigned j = 0; j < n.size2 (); ++ j)
            n (i, j) = 2 * i + j;

    mn = block_prod<matrix<double>, 1024>(m, n);

    return 0;
}

但我得到这些错误:

newfile.cpp:88: error: ‘block_prod’ is not a member of ‘boost::numeric::ublas’
newfile.cpp:88: error: expected primary-expression before ‘,’ token
newfile.cpp:88: error: no match for ‘operator>’ in ‘1024 > (0, n)’

我到处搜索，但找不到这些错误。我很欣赏任何想法。谢谢
