Computes the maxima (for each fixed value of the time variable) of the modulus of a continuous wavelet transform.
tfgmax(input, plot=TRUE)
wavelet transform (as the output of the function cwt
)
if set to TRUE, displays the values of the energy as a function of the scale.
values of the maxima (1D array)
positions of the maxima (1D array)
