#include <boost/numeric/ublas/matrix.hpp>
#include <boost/numeric/ublas/io.hpp>
using namespace boost::numeric::ublas;
matrix<MyObject> m_MyObjects(nRows, nCols);
I have a ublas matrix of objects as declared above... Is there a way
within the Boost lib (i.e. something I don't have to write much custom
code to use) that I can use to sort the matrix by a value of one
of the data members of MyObject? For example
If
class MyObject {
int thisOne;
}
and
m_MyObjects(0,0).thisOne = 1;
m_MyObjects(1,0).thisOne = 0;
m_MyObjects(0,1).thisOne = 4;
m_MyObjects(1,1).thisOne = 2;
It will sort the matrix so that
m_MyObjects(0,0).thisOne = 0;
m_MyObjects(1,0).thisOne = 1;
m_MyObjects(0,1).thisOne = 2;
m_MyObjects(1,1).thisOne = 4;
