Morlet Wavelet
Description
Compute the Morlet wavelet on a regular grid.
Usage
morlet(lb = -4, ub = 4, n = 1000)
Arguments
lb, ub
Lower and upper bounds of the interval to evaluate the wavelet
on. Default: -4 to 4.
n
Number of points on the grid between lb and ub (length
of the wavelet). Default: 1000.
Details
The code m <- morlet(lb, ub, n) returns values of the Morlet wavelet
on an n-point regular grid in the interval c(lb, ub).
The Morlet waveform is defined as
\psi(x) = e^{-x^{2}/2} cos (5x)
Value
A list containing 2 variables; x, the grid on which the Morlet
wavelet was evaluated, and psi (\Psi), the evaluated wavelet
on the grid x.
