FWT_TI {waved} | R Documentation |
Compute the Forward Wavelet Transform of a signal $f$ for the Meyer wavelet (translation invariant).
FWT_TI(f_fft, psyJ_fft)
f_fft |
vector of the Fourier coefficient of $f$. |
psyJ_fft |
vector of the Fourier coefficient of the Meyer wavelet. |
vector of wavelet coefficients (non-ordered).
