Sorting Toolbox

About

Sorting Toolbox contains algorithms that are used to put elements of a list in a certain order. Efficient sorting is important for optimizing the use of other algorithms which require input data to be in sorted lists.

Features

  • buildHeap - builds heap structure from a list for heapSort and priority queues (based on heapify)
  • buildQ - builds priority queue structure from an adjacency matrix and priority list (based on heapify)
  • extractHeapMax - extracts the maximum element from a heap (used for priority queues) (based on heapify)
  • extractHeapMin - extracts the minimum element from a heap (used for priority queues) (based on heapify)
  • extractQMin - extracts the smallest priority (key) element from the priority queue
  • findQ - finds an item in the priority queue
  • heapSort - comparison-based sorting algorithm /by Williams/
  • insertElemToHeap - inserts a key element to a heap
  • insertionSort - insertion sort algorithm
  • mergeSort - comparison-based sorting algorithm /by John von Neumann, 1945/

Note: globalConsts.m initializes global constants
