Final mean square distortion, returned as a positive scalar. The function calculates the mean square distortion at each step of the Lloyd algorithm. Final relative change in mean square distortion, returned as a positive scalar. If the algorithm terminates because of the first condition inAlgorithms...
最小堆与最大堆实现细节: 使用vector和algorithm中的函数make_heap, pop_heap, push_heap, sort_heap就可实现最小堆与最大堆。例如: max.push_back(num); push_heap(max.begin(), max.end(),less<int>()); num= max[0]; pop_heap(max.begin(), max.end(), less<int>()); max.pop_back();...
