Python interface to harminv
Project description
This is a python interface to harminv, a library for performing harmonic inversion on a signal.
Requirements:
BLAS & LAPACK
libharminv-dev
numpy
Installation:
Make sure that you have the requirements above, then
pip install pharminv
Usage:
harminv.invert contains the basic functionality of the harminv tool. This function should remain stable but the API elsewhere is subject to change.
import numpy as np
import harminv
time = np.linspace(0, 1, 1000)
signal = np.cos(2 * np.pi * time * 10) + np.cos(2 * np.pi * time * 20)
inversion = harminv.invert(signal, fmin=1, fmax=100)
inversion.freq # mode frequencies
inversion.decay # decay rates
inversion.Q # Q factor
inversion.amplitudes # absolute amplitudes
inversion.phase # phase shift
