vector sort_indices( vector )vector sort_indices( vector,string ) |
Performs the same sorting as the sort() function, but instead of returning the sorted values, it returns the indices ofwhere the sorted values lie in the original vector. For example:
v1 = |5, 3, 4, 9, 1, 4.2|
sort(v1) # returns |1, 3, 4, 4.2, 5, 9|
sort_indices(v1) # returns |5, 2, 3, 6, 1, 4|, e.g. the 4th sorted number is the 6th element from the original
