Sparse Matrix non zero elements in each row

[Shamika Mohanan]

I'm creating a sparse matrix using Octave in c++ code. The code is-

octave_value_list out = feval (pstData[0], in, 1);
if(out(0).is_sparse_type())
{
  SparseMatrix sparse_matrix=out(0).sparse_matrix_value ();
  int iNbItem= sparse_matrix.nnz(); //Get number of non zero elements in sparse matrix
}

How do I get the number of non zero elements in each row and the column indices of the non zero elements?
