pharminv 0.2.1

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
