Fourier Transform with irregularly spaced x
Dear all,
I work with (vibrational) spectra: some kind of intensity (I) over frequency
(nu), wavelength or the like.
I want to do fourier transform for interpolation, smoothing, etc.
My problem is that the spectra are often irregularly spaced in nu: the
difference between 2 neighbouring nu varies across the spectrum, and data
points may be missing.
