scripts default iconfftnoise - generate noise with a specified power spectrum (Scripts) Publisher's description

USAGE: noise=fftnoise(f[,Nseries])

USAGE: noise=fftnoise(f[,Nseries])

f: the fft of a time series (must be a column vector)
Nseries: number of noise series to generate. (default=1)

noise: surrogate series with same power spectrum as f. (each column is a surrogate).

------ Example: ------
%calculate if the trend is significantly different from zero
%(Null-hypothesis: a random process with the same power spectrum as data).

for ii=1:size(psur,2)
ptile=prctile(psur(1,:)',[2.5 97.5])
if (pdata(1)>ptile(2))|(pdata(1)<ptile(1))
disp('significant trend')
disp('not significant trend')

System Requirements:

MATLAB 6.0 (R12)
Program Release Status: New Release
Program Install Support: Install and Uninstall
