%description
Harminv is a free program (and accompanying library) to solve the problem of
"harmonic inversion." Given a discrete, finite-length signal that consists of
a sum of finitely-many sinusoids (possibly exponentially decaying), it
determines the frequencies, decay constants, amplitudes, and phases of those
sinusoids.

It can, in principle, provide much better accuracy than straightforward FFT
based methods, essentially because it assumes a specific form for the signal.
(Fourier transforms, in contrast, attempt to represent any data as a sum of
sinusoidal components.)
