Harminv 1.3.1

Harminv is free software and a library for C inversion harmonic. Harminv is a free and a C library for harmonic inversion: decomposing a time series into a sum of sinusoids, including sinusoids.Harminv exponential decay is based on the method "filter diagonalization (FDM) of Mandelshtam & Taylor, Matches the harmonic inversion problem on a small eigen problem (size proportional to the number of sine waves). The FDM is often able to obtain solutions more robust and more accurate than alternative methods.What 's new in this version: § An opposite sign convention used for the output stage has been set.
