fronts.sorptivity
- fronts.sorptivity(o, samples, *, i=None, b=None, ob=0)
Extract the sorptivity from samples of a solution.
- Parameters:
o (numpy.array_like, shape (n,)) – Points where \(\theta\) is known, expressed in terms of the Boltzmann variable.
samples (numpy.array_like, shape (n,)) – Values of \(\theta\) at o.
i (None or float, optional) – Initial value \(\theta_i\). If not given, it is taken as
samples[-1].b (None or float, optional) – Boundary value \(\theta_b\). If not given, it is taken as
samples[0].
- Returns:
S – Sorptivity.
- Return type:
