Hi,


There is a set of data contains deterministic component and noise. I want to obtain the noise variance out of these data in matlab.
The way I did is to divide the set of data into a number of small segments and calculate variance of variance of each segment. The total variance is just mean value of them.


My question is is there any way that I can do this faster?
Thanks a lot.
