cwt
returns a matrix of wavelet coefficients for the specified scales.
1 | cwt(obs, scales, psi = "mexh")
|
obs |
vector of the time dependent signal. In our case, intensities. |
scales |
vector of the wavelet scales which to apply. |
psi |
the wavelet to apply. "mexh", "nmexh" or a data.frame containing the wavelet. |
This function is a modification of the original cwt code provided by the centWave algorithm [1], [2] and [3].
A matrix, rows corresponding to wavelet scales, columns to time.
This code was modified from the originally published centWave algorithm [1]. The code was orginally distributed and obtained under the GPL2 license via the xcms software package [2]. The original algorithms depend on the wavelet analysis code included in the MassSpecWavelet package [3]. All code herein was obtained under the GPL2 license and remains under the GPL 3 license or greater.
