dcmri.conc_comp

dcmri.conc_comp(J, T, t=None, dt=1.0)

Indicator concentration inside a compartment.

See section Compartment for more detail.

Parameters:

• J (array_like) – the indicator flux entering the compartment.

• T (float) – mean transit time of the compartment. Any non-negative value is allowed, including \(T=0\) and \(T=\infty\), in which case the compartment is a trap.

• t (array_like, optional) – the time points of the indicator flux J, in the same units as T. If t=None, the time points are assumed to be uniformly spaced with spacing dt. Defaults to None.

• dt (float, optional) – spacing between time points for uniformly spaced time points, in the same units as T. This parameter is ignored if t is explicity provided. Defaults to 1.0.

Returns:

Concentration as a 1D array.

Return type:

numpy.ndarray

Example

>>> import dcmri as dc
>>> t = [0,5,15,30,60]
>>> J = [1,2,3,3,2]
>>> dc.conc_comp(J, 5, t)
