sorting a time series

Hello,

II have a time series Yt and I sorted them in ascending order and I got Yi, then I used them in a function and I got Zi as Zi=F(Yi), How can I rearrange Zi to Zt (the same order of Yt)?

You need to use the optional output from the sort function that contains the sort order.

[Y, idx] = sort(time_series);
Zt = Zi(idx);

hi, you apply directly the function Zt=F(Yt) as :

 (Yt,Yi) =>:  F(Yt,Yi)=(Zt,Zi)
