In wsyn: Wavelet Approaches to Studies of Synchrony in Ecology and Other Fields

Description

Worker/utility function serving the analysis carried out in synmat for methods based on coherence or real part of the cross-wavelet transform.

Usage

wavmatwork(dat, times, scale.min, scale.max.input, sigma, f0, norm, treatment)

Arguments

dat	A locations (rows) x time (columns) matrix of measurements
times	The times at which measurements were made, spacing 1
scale.min	The smallest scale of fluctuation that will be examined. At least 2. Used only for wavelet-based methods.
scale.max.input	The largest scale of fluctuation guaranteed to be examined. Only used for wavelet-based methods.
sigma	The ratio of each time scale examined relative to the next timescale. Should be greater than 1. Only used for wavelet-based methods.
f0	The ratio of the period of fluctuation to the width of the envelope. Only used for wavelet-based methods.
norm	The normalization of wavelet transforms to be used. One of "none", "phase", "powind".
treatment	Either "Mod" or "Re"

Value

wavmatwork returns a list consisting of:

timescales	The timescales of analysis
wavarray	An array, locations by locations by timescales, containing either the coherences (for treatment="Mod") or the real parts of the cross-wavelet transforms (for treatment="Re") between locations.

Note

Internal function, no error checking done.
