Could you tell me the algorithm and/or the running time of the SORT function?
I need to know which sorting algorithm is used by MATLAB when the SORT function is executed.

The type of sort that is done is a Quick Sort. It is not an 'adaptive sorting' algorithm, and does not deviate much from the standard Quick Sort algorithm. Quick Sort has been found to be one of the fastest algorithms for sorting; it is an O(n log n) operation. We do not have specific time information, since it depends on both the system and the numerical data used in the sort.
