Hey guys,
I have 2 vectors here, time [23 4 8 9 21 3 11 15 17 2] and signal [12 14 11 13 16 5 31 21 9 3]. What I want do is quicksort time into ascending order (i.e time =2 3 4 8 9 11 15 17 21 23] ). However, I also want the signal to rearrange itself accordingly, so it becomes [3 5 14 11 13 31 21 9 16 12]. How would I go about this???
Kind regards,
Tom
P.S I'm not allowed to use the sort command

See the 2nd output of the sort( ) function, and use that as an index to rearrange your signal. E.g.,
[t,x] = sort(time);
s = signal(x);

What have you done so far? Are you having trouble getting started? Are you getting errors in your code? Do you have a working quicksort routine and just need to figure out how to get the indexes? Or ...?
