Coherence estimate using multi taper
in [Matlab]
|
From: Atreyee Bhattacharya on 8 Oct 2009 15:42 Hello, I am pretty new to Matlab. I urgently need to do the following with my data 1. powerspectrum using multitaper 2. Cross spectral analysis and coherence estimate using multitaper method 3. Putting a 95% confidence interval on all of the above. This may be a lot. But I absolutely have to do this. Any help is greatly appreciated Thanks Atreyee

Any help is greatly appreciated Best be gettin' busy, then... if you have the Signal Processing toolbox lookfor spectrum lookfor taper otherwise, it'll be starting from the basic FFT and definitions but it is a _fairly_ straightforward process... --
