I have a list which is almost surely some sort of a wave-like oscillation:
y(x): {{x_1, y_1}, ...,{x_n, y_n}}
and want to find wavelets that interpolate this data best using Mathematica. However, Mathematica's wavelet toolbox accepts standard sequential (uniform) series rather than non-uniform grids.
Possible solutions are either to firstly interpolate y to a uniform x grid and then proceed with wavelet decomposition or to find a fit to wavelet functions explicitly using FindFit routines without referring to the toolbox.
Is there any other solutions?
