flt_dbl calc_euclidian_distance( sparse_flt_dbl_vec & datapoint,  flt_dbl_vec &cluster, flt_dbl sqr_sum, flt_dbl sqr_sum0){
  flt_dbl dist = sqr_sum + sqr_sum0;
  //for (int i=0; i< datapoint.nnz(); i++){
  FOR_ITERATOR_(i, datapoint){
      flt_dbl val = get_nz_data(datapoint, i);
      int pos = get_nz_index(datapoint, i);
      dist -= 2*val*cluster[pos];
   }
