find_integer_vectors

superfreq.find_integer_vectors(freqs, table, max_int=12)

Given the fundamental frequencies and table of all frequency components, determine how each frequency component is related to the fundamental frequencies (e.g., determine the integer vector for each frequency such that \(n\cdot \Omega \approx 0.\)). These are the non-zero Fourier modes.

Parameters:

freqs : array_like

The fundamental frequencies.

table : structured array

The full table of frequency modes, amplitudes, and phases for all components detected in the FFT.

max_int : int (optional)

The integer vectors considered will go from -max_int to max_int in each dimension.

Returns:

nvec : numpy.ndarray

An array of integer vectors that correspond to the frequency components.
