A C89 testcase:
struct TSparseEntry
{
 int feat_index;
 double entry;
};
struct TSparse
{
 int vec_index;
 int num_feat_entries;
 struct TSparseEntry* features;
};
void
get_full_feature_matrix(struct TSparse* sparse_feature_matrix, int num_vec)
{
   double* fm;
   int v, f;
   for (v=0; v<num_vec; v++)
    {
     for (f=0; f<sparse_feature_matrix[v].num_feat_entries; f++)
     {
      long long offs = sparse_feature_matrix[v].vec_index 
           + sparse_feature_matrix[v].features[f].feat_index;
      fm[offs]= sparse_feature_matrix[v].features[f].entry;
     }
    }
}
