A typical scenario to insert nonzeros is illustrated bellow:
\code
1: SparseMatrix<double> mat(rows,cols); // default is column major
2: mat.reserve(VectorXi::Constant(rows,6));
2: mat.reserve(VectorXi::Constant(cols,6));
3: for each i,j such that v_ij != 0
4: mat.insert(i,j) = v_ij; // alternative: mat.coeffRef(i,j) += v_ij;
5: mat.makeCompressed(); // optional
