dtmean: spatial mean spectrum

Description Usage Arguments Value Note

View source: R/spectra.R

Description

average the output of fld2dt or dtcwt over space

Usage

1
dtmean(x)

Arguments

x

either a J x nx x ny x 6 array of energies (output of dtcwt) or a list of complex wavelet coefficients (the output of dtcwt(...,dec=FALSE))

Value

a J x 6 matrix of spatially averaged energies

Note

In the undecimated case, the coefficients are not averaged but summed up and then scaled by the area of the first level. This yields a comparable scale as the undecimated case.
