Hi everybody
I have a time series which I would like to decompose into a trend, one
or more seasonal signal and a noisy signal.
all this with matlab.
I managed to extarct the trend, but for the two others part I am
struggling a lot so could anybody give me some advises on how to do
that with matlab? some easy to use tutorial on that subject linked to
matlab? some functions or some programs already written?
thanks a lot
best regards
Yoann
