skrf.vectorFitting.VectorFitting.plot_s_singular

VectorFitting.plot_s_singular(freqs=None, *, ax=None)[source]

Plots the singular values of the vector fitted S-matrix in linear scale.

Parameters:

  • freqs (list of float or ndarray or None, optional) – List of frequencies for the response plot. If None, the sample frequencies of the fitted network in network are used. This only works if network is not None.

  • ax (matplotlib.Axes object or None) – matplotlib axes to draw on. If None, the current axes is fetched with gca().

Returns:

matplotlib axes used for drawing. Either the passed ax argument or the one fetch from the current figure.

Return type:

matplotlib.Axes

Raises:

ValueError – If the freqs parameter is not specified while the Network in network is None.
