How to get sorted index order for an array?
显示 更早的评论
For example, if I use the sort function on the array [14 8 91 19], I will get [8 14 19 91]. But instead I want [2 1 4 3] which gives me the indices of elements in the original array.
Is there any inbuilt function or does the sort function accept any additional argument to accomplish this? Otherwise I have to write my own function.

You can obtain the output indices directly from sort:
>> [out,idx] = sort([14 8 91 19])
out =
8 14 19 91
idx =
2 1 4 3
