-This means that in general the 'spline' method results in smooth
-results. If the function to be interpolated is in fact smooth, then
-'spline' will give excellent results. However, if the function to be

-interpolation might give better results.

 Fourier interpolation, is a resampling technique where a signal is
 converted to the frequency domain, padded with zeros and then
 reconverted to the time domain.

 To correct this behavior would mean that zero elements with a negative
