I am trying to figure out how to print the non-zero values in an Eigen SparseMatrix along with the indexes. So, in matlab combined with C++ speak something like:

Code: Select all

Eigen::Sparsematrix<double> mat;
std::cout << mat(10, :) << std::endl;


This for example could print all the non-zero values in the 11th row along with their indexes. Something like:

Code: Select all

         (10,1)              6
         (10,2)             -6
         (10,3)              1
         (10,33)            -6
         (10,34)             4
         (10,65)             1
